If you want a second report template you can duplicate the one you already created to work from there.
You have a league that has a few different stats you want to show, you can copy the one you already have, and make modifications to your new one.
Please note: YOU DO NOT NEED A REPORT PER LEAGUE. IF YOU WANT TO SHOW THE SAME STATS (Points, Wins etc) USE THE SAME STAT REPORT AND CHOOSE THE LEAGUE YOU WANT TO PULL STATS FOR.
The report is a template, the system then shows the stats of the league you want. You only need a second report if you have a league that scores differently or ranks differently for example.
To duplicate a report:
Menu > Manage > Reporting > Standing Report Editor.
1. Choose a Round-Robin, that will serve as an example in the display to the right.
2. Select a report in section 1 by clicking on it.
Click on Duplicate.
Rename your new template and personalize it by changing stat columns etc.
