Allow clan leaders and or a limited number of co-leaders to set their accounts to auto donate troops to clan mates.
Another option would be to allow clan or co leaders to push troops to clan mates castles that are empty in order to support their defense.
this could be controlled or limited in a variety of ways.
have leaders or co leaders buy this option with gold or elixir with a time designation between purchases so as to be strategically used and discourage abuse or the loading up of clan mate castles in an unfair advantage.
