Ahh, I see what you want.
This has been wished for before.
The problem is a zone does not have to be a rectangular shape.
It could be any shape.
Even if it was rectangular it could be horizontal, vertical or at any angle of rotation.
I have an object I place with moveable hotspots I can stretch to where I want.
I guess if somebody wanted to they could script some hotspots into a zone stamp to save having to use a separate object like I do.
