The Copy Roster function makes it easy to use an existing roster as a base for a new Roster, especially when the rules on the roster are similar.
To copy a Roster, go to Settings > Practitioners > Rosters
Open the Roster you wish to copy and select the options menu (3 dots) at the top of the page.
Select the Copy Roster option, which will take you to a new page with a copy of the selected Roster.
Once you've finished editing the copy of the Roster, select Save.
