Adult baseball league schedule

Trying to simplify a league schedule.I currently do everything manually

need a master schedule for X# of teams (may vary season to season)
I'll upload what I did for the spring season for 7 teams and the fall so far for 7 teams
looks like this fall season may have up to 10

similar to a round robin schedule with full game schedule every Sunday for spring season
the fall adds in a single game for Monday and Friday nights

any help would be appreciated
thanks
