Assign a group by category for a given user (PrestaShop 1.6)

[vincebdev]

Hello everyone,

I'm looking to add a group to users by existing product category.
I explain, I would like user "A" to have price group "group1" for category "cat2", price "groupZ" for category "cat4" for example.

I don't know if this is clear enough in writing 😅

This doesn't seem to be possible natively.
I am willing to develop it if needed.

Not knowing the PrestaShop architecture precisely yet, a little help from the community would be welcome.

Thanks to all.
