Add new club feature please?

I'm creating a club right now but I just can't decide on a good tag. There is no way to change your club tag once you click "Create" and so after I create it and decide I don't like it, I have to kick every member in the club and then remake. Can Riot at least add a button that checks the if the tag is available? Maybe putting an "Availability" button next to the "Create" button. Even better would be the ability to CHANGE the club tag.
