You can't - at least not easily.

You could use a complicated qdiskd heuristic to do this, or you could
simply use a simple application which bumps quorum counts based on
resource location(s) (such an app doesn't really exist today, but is not
difficult to implement).

Basically, the infrastructure (membership/locking/fencing/etc.) is a
separate entity which is not tied to service management.  Put another
way, while the rgmanager relies on events from CMAN, the reverse is not
true.
