Separate barracks & army camp for troop donations to clan members,1 in-battle update

I didnt see any thread with this topic so I'm not sure whether it has already been discussed. It will be great to have a separate army camp and barracks just for donating troops in wars and for clan castle requests to our clan members which can instantly train troops. As it gets irritating to wait a long time for the troops to train when more than 4-5 people request for troops at the same time.
Another suggestion is please allow us to choose which building a certain group of troops attack in-battle (not referring to favourite building) because its highly disturbing when dragons attack everything other than an air defense.
Lastly, even though it has already been ruled out, a second laboratory and boosting builders.
A reply will be appreciated! (especially if you're going to delete this post) :)
Thank you.
