[TEAM BUILDER][SUGGESTION] A New Button in Team Builder When Searching For Other Players?

I've been playing Team Builder more and more often in the last few weeks. Usually I invite 2-3 friends to play with me. As soon as everyone has finished with their settings for Runes, Masteries, Skins, etc. I start looking for Solo Players. The problem here is that as soon as I click "Find Solo Players" and "Search", there is no way back. For example, my team and I are looking for a jungler but I accidentally entered top lane and clicked search. From this point I have to delete my team and have to reinvite everyone again and they have to do all their settings again. So hours are passing. What about a "Stop looking for players" button or something with that intention. I could really use it if i decide to invite a few more buddies or if I made a mistake.

In this very artsy picture you can see that I made a mistake when locking in the players (Two Midlaners). As I am alone in this example, I could just quit but to make it easier there should be a button like the one I drew, e.g. "Stop looking for players". It would make the Team Builder experience way more enjoyable and easier.

Thank you for throwing an eye on my suggestion!
