I have an entity called waiting list where I put all of our contacts that are waiting to come on a trip with us. After the person on the waiting list comes on a trip, I want to remove them from the waiting list and add them as an official contact. Is there a way to do this without entering all of the data again? Waiting list and official contacts are 2 different entities. Some of the fields are different between the two where they will have to add and remove some additional information.
