[SDF-25815] Support group to multiple sites

Hello! Is there a way to have the same support group to be associated with multiple sites? In our case we have several groups that serve multiple site users, and right now the only way I see to configure this is to create a different "copy" of each group with the same technicians for each one, which can be cumbersome in the long run.
