I have a question on Matching rule of Event Administration as the following scenario:
1) In Event Administration, when a customer submit a registration in Event (required fields is First Name, Last Name and Email Address), system can create new Contact or map the event registration to an existing Contact without update First Name and Last Name of an existing Contact. So we had set the value of "Match contact based on" field is "Email". So when a customer submit the registration on Event, the event registration can map the email on a event registration to an existing Contact and don't change the First Name and Last Name of that Contact.
2) After a customer submit the event registration, they refer the email confirmation to send the First Name and Last Name that they have submitted before but not the First Name and Last that already exist in the system. So the question in this situation is: How can we collect the First Name and Last Name of the customer when they submit the Event registration, but without update the First name and Last Name of Contact that already existed?
We are considering about Custom registration fields, but if anyone have a solution on this case, please help us to rise it.
