It would be very helpful to be able to que up building upgrades the same as troops.All the farms and buildings that can be upgraded and only 1 at a time? It would be a lot easier if you can "stack" upgrades. It would be nice to cue up 5 farms for upgrade while I'm at work so time is not missed in between upgrades.It is cool now but sometimes it's a bit of a drag to upgrade a building that takes 1-2 hours and I'm on my way to sleep.i only get 1 building upgraded cause I'm sleep and can't cue up next one.So to help that,allow us to "stack" building upgrades so we never skip a beat.
