You can change the To Location in the phase. For details on how to change the To Location, refer to Update the Occupant's To Location.
It is important to remember that any changes will automatically Sync Forward to future phases and never backward to past phases.
In this example:
In Phase 1, John was added and moved from 9.1 to 9.2.
In Phase 2, John was added and moved from 9.2 to 9.3.
In Phase 3, John was added and moved from 9.3 to 9.4.
Then back in Phase 2, John's To Location changed to 9.6. This will result in the BOS Move Row being deleted and the Sync Forward will delete the BOS Move Row in future phases.

Remember when you publish a phase to the Live VBS you will have the following options:
