Clan Castle reinforcement switcher

Clan castle reinforcement, is well doesn't have to emerge out of the clan castle while village is under attack right?
What if you don't want them to deploy while being under attack, so you don't have to worry about them and that you'll have to request troops again for clan wars?
In this thread, i want an update which gives you an option for the clan castle reinforcement to deploy/not to deploy while being under-attack.

I hope you read this thread and give an update to it

and as always, Clash on!
