Easy fix for reserving bases in clan wars

In clan wars, especially large wars, it becomes increasingly hard to organize attacks. Many have turned to third party programs (Clashcaller and Clashofclanswarplan) in an effort to fully plan their wars. The problem is not everyone signs up for these sites and I have to repeatedly post which bases have been called or reserved. If you could add a button next to each enemy war base so that when a player clicks it, his/her name appears next to that base as reserved, it would help lessen confusion. If a player changes his mind, he/she can click it again to cancel their reservation. I've drawn up a little mock of how it might look like. "O" to reserve. "X" to cancel.Attachment 119141
