Set CC troops to sleep mode-don't come out when attacked

Sorry if this is ruled out and I didn't notice it in the list, I don't think it's there.

Before a clan war sometimes your clan mates give you high level troops for the war and you get attacked overnight and they are gone when the war starts.

Could we have a way to set them to sleep mode where they don't come out and therefore don't die, or guard mode where they defend your base? Like heroes

Also, staying online isn't an option because I'm not going to stay up all night for Clash and also you get kicked off for playing too long.

This has been suggested before. However, it has been asked for for a very long time, I don't think it is ruled out, and it is overdue. Definitely need this.

yes, it has already been requested several times. i think it is a smart idea due to recent updates, and i believe coc will add the sleep mode feature soon

I think this will be very beneficial. I have been in that place,as I'm sure many people have and it is extremely annoying.Yes, you could just wait til b4 you attack,but maybe someone can't be on to give exactly what's needed.
