Char. and options not behaving as expected

-- HikaShop version -- : 2.4.0
-- Joomla version -- : 3.4.1
-- PHP version -- : 5.5.24
-- Browser(s) name and version -- : Chrome is best
-- Error-message(debug-mod must be tuned on) -- : No error message.

We are very pleased so far with Hikashop, it provides more and more possibilities. Currently we have a need to offer options with our products. This must be done in such a way that each product can have a different subset of values for a characteristic. Unwanted values need to be deleted. Also, the values can come with different product-specific pricing, depending on what product they are for.

Hikashop seems able to partly do this, there are two (partial) ways we have found. In the product attributes page:
1. Using the "Options" section: the standard values and pricing is used, all values are presented, but it is not possible to have other pricing or to delete unwanted values from the list.
2. Using the "Characteristics" section: here, after adding the characteristics, the values are created with a product-specific code. It is therefore possible to delete unwanted values. It is also possible to add other prices. However, the prices are not visible in the drop menu on the front end. And the calculations result in strange effects on the product page, wrong pricing for the main product, wrong calculation of total.
Please see the images supplied.

How can we achieve the best of these 2 world. Our products need:
A. Only the values relevant for the product should be visible.
B. The prices of the product-specific-values which can be selected should be visible in the drop menu.
C. The calculations should be correct and visible on the front end, with the price of the basic guitar remaining visible.

Can you help with this? If you like, we can give direct access to that you can see the workings directly.

Kind regards,

Ok, thanks.
I was under the impression that there is a very solid underlying datamodel, which is excellent. And that this datamodel allowed for having an option, say in the case of guitar: finishing in gold, silver or bronze, which will differ in price depending on the type of guitar, for instance bass or electric, electric or acoustic. And many other options such as type of hardware, pickups, etc. And the only think differing is the price. It would be so much less maintenance if I had been able to only register the gold, silver and bronze finish once, and add the say 100 guitars once. And that the options when used for a particular type of guitar just got a different price. That way I would only need to add those three options, and 100 guitars, and add the price only to that relationship. If I understand you correctly, I will now need to create 300 options instead of 3. Namely gold-guitar-1, silver-guitar-1, bronze-guitar-1... then gold-guitar-2, silver-guitar-s, bronze-guitar-2, each time with the prices. So I will have 100 guitar products and 300 options to maintain, instead of 100 guitar products and 3 options.
This creates a tremendous amount of work, I hope you can have a look to see if this can be looked into to simplify this so that instead of maintaining 300 options here, we can just revert back to maintaining the three options with the price being determined on the relationship between guitar and finish-option.
Alas, for now I will have to do it the cumbersome way I fear.
Thanks for advising.
