Currently, you'll need to shift people separately when you shift phases. However, this can be done very quickly using our multi-select tool.
Move your phase to the desired time.
Click on the 3 buttons on the right of one of the assign connected to the phase you just moved. You'll see a new menu. Click on "Enable "Multi-Select Mode".
2. Select the other assignments that need to be moved (should be in the same color) and then drag them to match the phase changes.
Multi-select mode will then automatically end.
