Membership - Concurrent Access Levels

I need concurrent access levels, or a workaround, as I am trying to use Membership integrated with Events, and certain memberships/subscriptions get access to more than one type of event.

a) Is this an existing feature request?
b) Is the status known?
c) Is there a workaround?

The problem seems to be in the design of the wp_m_subscriptions_levels table, where Subs and ALs are related 1:1.

Since I am not really doing Access control, is there some relatively simple hack where I can modify a function or two to look in a newly added table for the Access Levels related to a Subscription?

Thanks!
