Add capabilities to a Membership level?

Is there a way to add specific/custom capabilities to all members of a Membership level?

I want to give some capabilities that are by default limited to admins, but I don't want to give these users admin roles. I figure since I'm using Membership 2 Pro, and will have a membership level just for these users, it would be great if I could manage the capabilities by membership.

Ideally there's a plugin that could do this, but I'd be okay with adding a function/action if I could get some guidance with the code needed.

The capability I want to give the members of the group is: gravityforms_edit_entries
