Actually... on further thought, if it's possible to do the box thing with objects inside that box there... then some boxes on the Lenningrad map would be absolutely amazing. We can't use that map at all online but it's the site of so many battles.
A north box with Vyborg/Viipuri (Karelian Isthmus battles) and another box south and to the east of Leningrad would cover sites of some major battles.
Possible?
