Here's how to create a printable reference of all of your formations in a single document without any play diagrams.
Tap to expand the "Categories" view in the play gallery.
Tap the arrow to the right of the Categories button.
Enter a name (ex. "Offensive Formations") for your new Category and tap the + icon.
You can rearrange categories by holding and dragging the = icon. For this example, we've rearranged our new "Offensive Formations" Category to the top of the list.
Go back to the play gallery and tap the "New Offensive Play" button.
We usually enter the play name as a "-" or "Reference", then select the first formation and our "Offensive Formations" Category.
Repeat the previous step until you've added reference plays for each of your formations.
In the Print setup window, select the "Categories" option, choose your "Offensive Formations" Category from the list, then tap "Print".
