Although the topic was not quite the same, I recently posted an
extremely small proof of concept module that demonstrates this. As Ratty
said, everything hinges on the use of the Map window-level setting where
you can specify a keystroke to be applied to all pieces ending movement
on the map. That keystroke fires a Trigger on your piece, and the
Trigger uses a property match expression to basically query if the piece
is now in a certain zone __and__ wasn't previously (to avoid spurious
activations of the Trigger from someone reorganizing pieces or moving
things around in the zone).
