Add product characteristic text to product code

I am using Characteristics on some of my store products, mostly related to clothing sizes. I have the configuration set to append the Characteristic to the product code, which is working when creating variants. However, the system appends the Characteristic ID. What I need it to do is to append the characteristic itself. So, for example:

I have a product code GS-1002 that has a "size" characteristic comprised of the options "S, M, L, XL, XXL". When the variant is created, I would like to see the following product codes:

GS-1002-S
GS-1002-M
GS-1002-L...

Instead, what we get is:

GS-1002_1
GS-1002_2
GS-1003_3...

Is there any way I can change this?

Thanks!!

Hi momentis,

You can edit the products code manually, in the product edition page click on "Manage variants" and click on a variant to edit, then you can change the product code.
