Can WP File Download display files divided in categories and only the ones visible to the user and user group?

I need to understand if your wp download plugin is suitable for my needs.
I need to create a section in a wordpress site, where a user can see ONLY the files he has the rights to see, divided by category (files are all pdf but i need to group by content).
Some files are assigned only to a user, some files are visible to a group of users, so if a file is assigned to a group, and if the user is a member of this group, he can see these files together with the files assigned to him.

I need to understand if your premium plugin permits to create a section like this.
I need also to know if i can have a refund if it doesn't.
Thanks.
