Suggestion : user role by category

For now, I use your plugin only to hide prices/cart buttons according to the role of users, not to manage prices.
For some categories in my store, I would like the prices to be hidden for a user role, but visible for another user role.
it seems that is possible with your plugin. But it is long to setting because it is necessary to define each product.
It would be nice to have an setting at the level of the categories.
