Hi,
Like that there is no option in HikaShop.
But you can add some custom code in the view in order to find if the current showing product is an option for another product (and then, display a link to that product).
It requires some PHP/Development skills ; but it is possible thanks to the view override system.
After that, I will recommend you to use some options like the one to group the options with the product.
In the product page, you have a popup link to see the details of an option (the "i" image).
Like here :
demo.hikashop.com/index.php?option=com_h...ow&Itemid=91&lang=en
It is easier for the customer because he can see the product page of the option without going out from the main product.
