I'd like a "multi-transfer" option similar to the "multi-attack" option.
At present, Warlight allows you to play with the Risk-ism that armies can travel faster through enemy territory than friendly with multi-attack, but not the reverse, what is far more realistic. This feature would address that.
It should not be hard to make, because it is very similar to multi-attack.
Please vote for it on uservoice:http://warlight.uservoice.com/forums/77051-warlight-features/suggestions/4515426-multi-transfer
