Allowing back end access to only some

Hi!

I’m using s2member pro with event espresso to create a membership site where users have access to register for free events. Right now I have it set in s2member to protect and block all users from the backend wp/admin areas. I want users to do everything from the frontend which I have set up and works fine. If they were to get access to the backend, it doesn’t allow them to get into anything sensitive but its not user friendly and it allows them to be able to cancel events which I don’t want and have blocked from the front end.

Everything is great with all of that except I need to allow Event Admins (a role in event espresso) to be able to get to the backend and input events/change users/ have access to the areas that I have checked for them in event espresso. Is there a way to only allow these event admins backend access?

When I uncheck block all, it gives access to all levels.

Thanks!
