Leader controlled war search match parameter

The clan leader should be able to select the range of clan war match tolerance that the clan is willing to accept. It should be noted that if you want a really close match that the time required to make the match will likely be greater while those willing to accept a greater variance in the match should have a shorter wait time. I am personally tired of sometimes losing 2 days due to reallly unbalanced matches and would rather have to wait for a couple hours in order to get a good war match. I would like to see it with several choices ranging between really close match (long matching time) and wide range of match (shortest waiting time).
