Clan Castle Troop Request

I feel as though there should be a click box with units, so when you post a request for troops you can just select which you would prefer to receive. Clan mates can look at your request and donate what is requested. That way in your chat box you don't have to keep changing what your request is based on what type of raid you are performing. It wouldn't change the world, but clarify what units people want. I get alot of:

Need Defense
Elixer raid troops
"Strong" units

Some make sense some are very subjective.

Just food for Thought!
