Clan castle additions!

Hey guys was thinking how it's real annoying when you have troops in your clan castle and you need them for the next raid, and then someone raids you and the troops activate in die in battle. It would be cool if you could set the troops on sleep mode or something like that, like how the heroes can guard the base or sleep. And another thing could be to set the castle on defensive or offensive mode, whereas the troops go to a defence (on defensive mode) and they man the machines in order to say add an extra 2 block radius to the defence or give it +2 hit points. Offensive mode would just be the same as it always is where troops go head on with the attackers troops.
