To war or not to war, that is the question

In many clans, there are a part time war members. It could be due to schedule or anything. With this scenario of real life, I would like to suggest a button that will give a player to choose to be in the war or not. The switch is as simple as ON and OFF switch. When it's ON, it means that the player will be included in the war. OFF it means that the player will opt out from war until the player turns it back ON again.

The switch is manual. It will always be ON until you turn it off. I hope this can be considered since I only have time to play in a day or two in a week. My clan goes to war whenever they have a chance except weekend. In order for me to be excluded, I had to leave the clan and rejoin the clan. This will reset all my donations counter.

I hope this can be considered and I hope is an easy one to implement. Thanks! :D
