Parent Team/ Sub-teams: Teams within a team

[#1]

It would be great to identify subteams within a parent team. For instance, our team of photographers and our team of stylists are both part of a larger "Studio Team". There are many subteams for the studio. When I add new people and choose "Photographer Team" for instance, they would automatically be included in the parent team as well.

I have a similar need. I found that you can create teams inside of groups, but you need to create the teams by adding individual users inside of the group. I would like to be able to add pre-existing teams into groups.
