WhenToHelp allows you to create multiple shifts per day for a helper, but tries to prevent you from "doublebooking" helpers to more than one shift at the same time. You cannot ADD an assigned shift that will overlap that helper's current shift but you can EDIT a shift and force it to double book.

There may be some instances that you do want to override doublebooking in order to schedule a meeting shift during a scheduled shift. You can do this using the shift change window:

• Add the shift as unassigned
• Edit the shift to assign the helper
• Click OK when warned the shift will conflict

To Assign a Helper to another shift at the same time as a current shift:
On the By Helper schedule view:

• If the shift does not exist, click the Add Shifts button
• Enter the shift information and leave it assigned to "None (unassigned)" and click the Add Shift button

• Click the unassigned shift in the schedule to open the Quick Shift EDIT layer.
• Click the link to Show Available Helpers
• Click the helper name in the list and click the Save button 
• When warned that they are already scheduled, click OK
