Clan Wars feature for clans only doing weekly wars

As a co-leader in a casual clan trying to stay together in the advent of Clan Wars, the most useful feature SC could add to help clans like mine is to create an opt out button players can toggle in the clan roster page.

Given that that might be a ways away, if ever- something that would appease our more serious warriors is to let the map of the last war remain, and you get two new attacks on that map. They don't count towards anything and the only reward is the pittance of loot each war base is equipped. This would let the players that want more practice have a chance at "that base i decided against attacking during the war cuz i needed to get a guaranteed 2-star".

I know the response would be "well just war again". Again, I stress we are a casual clan where most players only want war 1/week (if that). we are a group that gets along well, and we're trying not to have this one new component of the game rip us apart as it has so many other clans.
