Once the appropriate setting is enabled, you can attach signed per-guest waivers to more than one booking.
First, navigate to Settings > General Settings.
1. Click the Per-PAX Waiver dropdown.
2. Select Retain unattached signatures for assigning to multiple bookings.
3. Click Save Changes.
Now, when you attach a signed per-guest waiver to a booking, the waiver will remain in the list for use with other bookings.
