shifting while engaged to multiple enemies

[larsdangly]

Here's a question on this topic that I'm not sure I know the answer to. In fact, I can't think of a passage in the rules that directly addresses it.

Consider a 3 hex figure who is engaged by two 1 hex figures. Thus, the larger figure is considered 'engaged' and is subject to all of the relevant restrictions on movement (though he/she/it can still 'push back' at the end of the movement phase). I think the rules imply that the 3 hex figure cannot use a a shift to simultaneously disengage from both figures, but can it use a shift to disengage from one while remaining engaged with the other? The conservative reading of the rules would say 'no', but I feel like an exception might be made because the 3 hex figure is not engaged by any one of the two individuals, only by the combination of the two. And the end result would be more realistic feeling.
