Ranked 5's Planning

Planning to play ranked 5's right now is a process that takes a lot of effort. I have to message about 10 people and eventually take lower plat or gold players. I am Currently Gold 1 in ranked 5's & Diamond 3 in Solo Queue. I had a team that was plat 3 but we were never able to play. The point is that Riot should make a page on Ranked 5's teams to plan out match times with teammates. Currently we have to use other media like facebook, google doc, or talking to every single person on league. If you add this feature it will be much easier to get a ranked 5's team rolling and get more serious games.
