There unfortunately is not. Apple's predicate control is unwieldy to say the least. Its content is binary encoded and contains serialized objects. It is impossible to modify it in a plist file and have it actually do anything.

When a filter gets extremely complex it is far easier to write an action which determines the filter's yes/no criteria. You can use the Stop Action and Filter Files statement. Basically it allows you to Close/Hide/Select files based on the contents of a track variable. Half the variable range is treated as strings while the other half are numeric.

The attached image describes a prototype for the action and also shows the filter definition.
