[1.7.3] - Module to add required personalization only for certain combinations

[GuerreraStyle]

Hello, I'm making a PrestaShop eCommerce for a client who sells sunglasses.

My problem is that some of those glasses are graduated glasses and I need tu activate an obligatory personalization (something like "upload your eye medical prescription") when the customer selects the "with graduated glasses" combination.

Right now I can only add a "requested personalization" field to a product for all combinations, so I had to create every product twice: one with graduated glasses and requested personalization field, and another one with regular glasses without it.

Can you suggest (or make) a module to achieve that?

Thank you.

btw the website is codesunglasses.it
