Replace map tile command

[left oasis]

It would be awesome if there was a command that combined the remove and add commands into a replace command for map tiles. Also the ability to swap the position of two tiles for map editing would be great as a command as well. (I know I could technically use the ghost hero special command but a dedicated one for map editing would be awesome)

Add is a replace

./special swap_systems tile_name: tile_name_to: is a thing
