Barracks troop training time revealed on donation screen

When you go to donate in chat or to war and press the "donate" button, troops available to donate are colored and those you don't have trained are greyed out. I would like a countdown timer over the greyedout troops, showing how long until they are ready to be donated (time until training done on that troop). Basically, just put the timer that is already on top of the barracks when troops are training, into the donation popup screen. I loathe hitting the red x on the donation pop up only to find out that the troop just finished training. Especially when donating to war because you have to return "home" then click war button then navigate back to team member's war base then hit donate.
