[Plugin: LeagueManager] Edit Team Goal Difference

Using version 3.6 in WP 3.0.1

I have updated the matches etc for a league but the committee have awarded a game to the opposition.

e.g.
Team A 5 – 1 Team B

So team A gets deducted 3 points and team B gets awarded 3 points, which is already easily done in the plugin.

I also require other fields next to +/- points that allows me to +/- goals for and against as the game was awarded and all goals need to be reversed but the fixture needs to remain as the original result in the match day and table.

Any help would be great

Thanks

Mark
