Customize the items variants pop-up table

Hi there, I need to create different item variants, I understand how to create them via the attributes but, I would like to know if I can customize the table that pops up when the user creates a new variant because I have to put a lot of attributes per item, and if I just kept it with the default view it would be a really long list of fields to fill, and I would like to make it more user friendly.

Thank you in advance!
