Hi Debbie,
Yes, that is correct.
Another solution could be creating different Admission items. For example, one admission item without insurance and the other admission item with the service fee attached to it.This way, registrants can chose which admission item to go for and whether they want the insurance or not.
Alternatively, you could create an optional item and name it Cancellation Insurance. Registrants will have the option to opt in for this or not.
I have sumbitted the above idea as feedback to our team as well!
Best,
Federica
