Trying to show events by level access (Events+ & Membership)

Hi,
I am working in a membership site with 4 level access and I would like to show events taking this into account.
I am using Membership and Events+ and I would like the users to see only their level access events, not all the events. Is that possible with these plugins?
In Events+ I have created 4 different categories and 4 different events (one assigned to every category). I was hoping to assign the event categories in the Membership Access Levels Positive & Negative Rules, but they are not there.
I don't know if I am missing something or if it's not possible to achieve that. Any idea on what to do?
Thanks in advance,
Xènia
