Showing/hiding a value on a unit?

Two questions:

First, is it possible to toggle between showing and hiding a text label on a counter? (I am under the assumption that layers are limited to fixed images - what I want to be able to do is, in a game where HQ units have both strength/movement and supply point values, have the owning player be able to toggle displaying the unit’s supply points on the unit.)

Second, is it possible to make a text label visible to the owning player but not the opponents?

– Don

Layer with transparent png/gif pictures of “1”, “2”, “3”, etc.

Or sometimes maybe easier to hide them with a rectangle picture which has same color than the background. Use that for value 0 and blank for all other for example.
