The only advantage I can think of being able to schedule or
force a backup of a server *now* without requiring all servers
in that same group to backup.

For this, you can use "DEFine CLIENTAction".  We have even set this up as a
script, so we can pass the nodename or comma-separated list of nodenames:
        run test_w_client NodeX
        run test_u_client NodeX,NodeY,NodeZ

I would avoid the "matrix" approach, if possible - maintenance could become
a real headache...
