Set the icon to (icon of another stack)

[Paul Claude]

To assign temporary an image to the button icon of your stack, Revolution
looks for the specified image first in the current stack, then in other open
stacks. But if you need to indicate an image of another open stack "X"
(without copying the image to your stack), you can assign this image to your
button only if this image has an id different from those in open stacks
loaded before the stack "X".

There is a way to tell to Revolution to look in stack "X" before the other
open stacks, even if they have been loaded previously?
