Notional supply status

[Courtenay]

Is there an easy way to see if the notionals in a hex are in supply or not before one launches an invasion? In a country, the answer will almost always be yes, but in a territory the answer is not always obvious, particularly if one is using limited overseas supply; sometimes I make mistakes, and it is embarrassing to make a +1 attack that one thought was going to be automatic. If you make the opposite mistake (a notional being out of supply and you not realizing it), you won't even have noticed the lost opportunity. (So at least you won't be embarrassed, unless someone else points out your mistake. [:)])
