Opt out button for Clan Wars

As not participating in clan wars can affect the whole outcome of war, can there be an opt out button, so if u can't take part u just are not in war clan.
This has to be easier than dropping trophies, which only works if you have not got the perfect amount of players for war, or leaving clan and returning after war has started.
Unfortunately for a lot of us, our real lives interfere with playing this great game, and clan wars has changed the game considerably, not for the worst, just changed the dynamics of game.

right now players can just leave clan and rejoin, however its too much hassle and makes players seems bad with good intentions)

This seems to be one of the most requested additions. Hopefully they will listen and add it soon.
