Hi,
The first step is to enter each of your teams in the 'teams' feature of your app. Then tick the box in 'teams' to create a manual schedule for each team. Then you can enter a schedule for each of these teams, so they display separately in your app by team. Then you can set-up a 'Duty Roster' for each schedule entered for each team.
And if you also create an 'access group' for each of these teams (via the website dashboard/ access groups), you can place members in those access groups, then the access groups you tick for each schedule will allow only those members in that group to take a duty for that schedule.
You can shuffle members in and out of access groups in bulk via your team's website dashboard / members / bulk edit members (via the 3 x dots icon).
Kind regards,
Craig.
