setup a grid overlay
A quick fix for not being able to combine large areas would be if you could make it easy to overlay a grid on the map so I can see which areas I have combined and can move to the next area which is as big as I can get and still combine. I am combining the maps into larger ones in photoshop

You can change the setting to display tiles grid in Settings dialog box.
