Allow contributors who are not part of my team to enter activities for my team

Can we add an additional team role below “Team Members” for people who aren’t a part of my team? This would allow them to enter “one off” activities for my team without actually being a team member. We could call them something like “Other Contributors”. Functionally, this role could be restricted so that 1) they could only see their own activities and 2) they could not view the display names of other team members. (Other Team members could see them however.)

The use case for this is that we often have people doing GAPP activities outside of their “official” team locations (e.g., I visited Bangkok for the weekend and was able to share with 5 people while I was there). Using the Bangkok illustration as an example, the advantages for this are 1) The Bangkok Team would be able to see and chain off the activities of the outside contributor and 2) the outside contributor activities would not show up or be counted in their real team(s).
