Set Wanted CC Troops

So one thing that really grinds my gears is when a clan member doesn't read my troop request and gives me something I don't want. I am in a pretty small clan (18 people but only about 12 are active/donate) so I usually have to wait a while for someone to see the request and then donate. If there was a way to set what troops I will accept so they can't donate other troops to me that'd make life much easier since I wouldnt have to drop them when I log back on and wait again.

An example of how it'd work is lets say I want 4 giants, a wizard, and an archer. When I request a dialogue can come up where I select which troops I want like in a troop/spell production building. And if I will take anything for some or all of the space then I can just leave it blank.

Seems like an idea someone else would have had at some point but I couldn't find it in the idea lists or doing a quick search so thought I'd throw it out there.
