Historical Stats

Great plugin, I’ve been testing football plugins for a few weeks now and this is the best I have come across. we are looking at moving our website from our current providers, which is geared towards football/sports clubs, as its very restricted.

I have managed to import players, matches, results etc and got our pages displaying how we want.

However there are a couple of things I would like to do through importing or updating files/database.
We have players with us for next season who have been with us a few seasons, so they have historical stats that we would like to move across, matches they started in or where subbed on, their goals, assists, cards etc.
I know I can manually edit each players stats for each season for goals, assists etc. And I can add them to the match lineups to account for appearances and sub stats, but those are both long processes.

Is there a way to do this by importing or updating files or the database?

Thanks
Tony
