Adding or removing roles from clusters of servers that are 30+ servers is a pain to do one by one. it simply takes forever.

It would be fantastic if I could mark all the servers that I need to manipulate roles on have one dialog box open. Add and/or remove the roles I need to change. When pressing OK my job is done: I've successfully added the 'awesome' role to 30 servers in less than 1 minutes.

Also this would make my management work less error prone as today I might have missed a server or two in the process.
