Stack inspection

Hi,
Is there a way to prevent your opponent to see all the counters of the stack, just the top unit.
I saw a thread where the solution of masking the units except the top one is suggested but, may be there is an easier solution ?
Thanks

I’d be interested in seeing a solution for this. Can somebody provide a link to that posting, and if there is an easier way (the original poster seems to think what has been proposed is difficult).

Also, I’m not entirely convinced it’s a good idea because in most wargames you’ll need to eventually allow your opponent to see those units to determine odds.

There are a number of games where the rules only permit you to inspect a stack below the top unit when a battle is actually initiated.In between battles, you are supposed to keep it in your head. Doesn’t really translate well to PBEM play, but makes sense for online play.
