Affiliate handling on coupons instead of link

Hi, as affiliates all want to sell by giving discounts, i asked my developer this:

or my partners i need to do 2 things:
1. open up every order to see which coupon is used.
2. select the order -> actions -> update the values -> partner id -> add partner number.

1. Can you make an extra column that shows the coupon used in the orders listing?
2. Can you make a button that does nr2 so i only have to add partner number?

If yes, please do. still same login for you. Let me know the costs .

Because updates could be an issue i added that a plugin/patch would be an option so he replied the following:

I have reviewed the HikaShop codes for the orders listing and details page.

It's more complicated than it appears, so here are two options:

Modify and extend HikaShop core files:
Not possible to create a patch, as HikaShop can change its codes. Applying an old patch may result in errors or non-functionality in other areas.
You won't be able to update HikaShop.
This is a low-cost solution.
Modify only the Orders Listing and Details page:
You need to replace 2 files (listing and details) after HikaShop update. Which you can done safely.
Additional queries/programming can be done by developing a custom component which won't visible to you at the Administrator.
You can update HikaShop.
This is a more costly solution.

Is there another way, or will this soon become a standard? How best to approach this in a way that i can quickly see in my orders which coupons are used and click to add the partner?
Alternatively the best solution would be to have the system add the partner+fee when their coupon is used. This would need the coupon to have an option to link to affiliate id number i guess.

Hope te learn! Kind regards.

Thanks, This was what i was looking for .

Just to explain, the column i hope to gain is a coupon column in orders listing, not the indeed already existing partner column.
But as i can now connect most partners to a coupon, it's not priority anymore .

The login details were inside the message to the developer.

And 1 more question about linking the coupon to partner:
I have 1 partner that had a hikashop customer account so it would not link in coupons. I added a Joomla user account for him but made a mistake in emailaddess. So changing the emailaddress it made a seperate user/customer in hikashop and when i do Action->update the values-> and pick an option to make the user and customer id match, i get a warning message that the emailaddress already exists.
Inside the Force affiliation in coupons i see () as the emailaddress is now without name and user

I will add a screenshot for 1. I do not have or see column option Coupon

for 2. Let me ask a question instead of rephrasing the issue:

How do i connect/fuse a Hikashop customer to a seperate Joomla user and have them both have the same emailadres?

Thanks

Thanks

I solved nr 1 with the latest update.
nr 2 solved itself with the update as well. That was a blessing
