I manage a group of 40 senior golfers and each M, W and Friday I have to submit a roster of the pairings for that particular day. My challenge is to make sure that the same people are not always playing together. I'm looking for a tool that would display a count of how many times Player A has played with Player B - Z; Player B has played with Player A, C-Z; etc? I've tried to use Pivot tables in different configurations but to date have not been able to display the result I'm looking for.
