Is it possible to flip a map?

I need to flip my whole map vertically - is there a way to do that? I don’t want the tile images themselves to flip, just the map of cells…

Thanks,
Bob

Currently flipping the active tile stamp will also flip the tiles. However, there is a script written by @eishiya that will perform the same flip, but without flipping the tiles:

You can select all tile layers in the Layers view, then select the entire map (Ctrl+A) and Cut (Ctrl+X), then use the above script to flip the brush and place it again as usual with the Stamp Brush.

The main downside is that it does not flip the objects. Those still need to be flipped separately, and for tile objects that would also flip their tiles (but they can be flipped back without affecting the position in the Properties view).
