A way to plan man management?

I would like to make long-term plans for who plays in which games, so my players get the proper amount of rest throughout the season. Trying to keep track game-to-game gets a little time consuming. I know I can look at the number of games played, but I was looking for a way within the game or if there is a program (other than an excel spreadsheet) to help me manage playing time.

Does anyone have any ideas?

YOu can customise the tactics view so that you can see how many games each player have played.
