Hi Lara,
Yes, the User Role Minimums plugin allows you to create quantity minimums for categories, and then assign those by roles or individual users.
If it’s not completely obvious, you need to set up “sets” of category minimums first, where you can then add as many categories as you want and specify a min and/or max quantity for each. You then can assign that set of category minimums to roles or individual users.
It’s also explained in the documentation here:
