Within
Teamwork.com, you can break your teams down
further by creating subteams.
Note: Subteams are available
on per-user Premium/Grow subscriptions and
above.
When you are creating a team,
you can make it a subteam by assigning a
parent team to it in
the Advanced tab.
Alternatively, click the three dots to
the right of a team in your teams list and
select Add subteam from
the dropdown menu.
When a user is added as a member of
a subteam, they will automatically be added as
a member of the parent team and any other
subteams above it in the overall team
hierarchy.
