I've been trying to figure out how to construct the conditions I need for a particular transition and as near as I can tell it's not possible to do what I want.  I drew a diagram to illustrate what I need:

I want to have several pairs of values ANDed then set up an OR for all of the results, which should require placing AND containers inside an OR container, but I don't see how that is possible in EPDM.  I can place multiple ORs into an AND, but not the other way around.

I hope that I'm wrong and that someone can show me how to create the boolean structure I'm looking for, otherwise I may have to break this out into multiple parallel transitions.  That would be possible, but I've got some 12 - 15 pairs of criteria to work with so I'd need that many individual transitions...
