Multiple Default Clearing Balancing Segment Values in 1 Rule?

I'm hoping someone here can help with a situation we have in one LE that really needs two different default clearing balancing segment values.  We would like to be able to setup an Other-Other intracompany balancing rule to have specific rules for 5 BSVs that will create entries using what amounts to a clearing BSV and the rest use another BSV.  But we can only enter one clearing bsv for the rule.
I've tried using the M:M and Default Rule combination but then the bsv I entered for the accounts is overridden by the actual (it doesn't really make sense anyway to use all other-all other to provide this information).  I don't know, we just need a way to tell the system to use X in some cases as the BSV and Y in all others.
