Grant Users Access to Multiple Teams

Team assignments and permission management

We have users segmented in different teams, Say Team A, B, C, D. While some users have access to view all contacts, some have access to view only their contacts or those within their team.

Currently, support has advised that there is NO way to assign certain users to multiple teams so that those that are restricted can also view select other teams contacts/deals etc?

The use case would be:

Say Tom belongs to Team A (leadership team), Sarah belongs to Team B (Europe Region). Tom would like Sarah to help work on his and other members in Team A, on their contacts and deals. Sarah needs to stay in Team B along with acess to all or selected members of Team A.
