Yes! And this is one of RosterBot’s coolest, most unique features. As we describe here in this tutorial, RosterBot’s Position Assistant allows you to create positions in any structure you like and for any sport, and subsequently players responding to invitations are slotted into the positions you set for them under the Roster menu.
This works well for making sure you have the right number of specialist players, such as goalies and/or pitchers, quarterbacks, etc.
To create positions, log-in and select the Position tab on the Navigation bar.
