I have some issue about updating prospect. Pardot Form Handler is checking the prospect before inserting it as new or updating an old one. No problem at this. I want it to update prospect if there was already same mail address. But I don't want to check only the mail address. I also want to check one more item. If both mail and (that) item is same. Then update the matching prospect. But let's say email address is same but the selected form item(example: name) is different. Then I want it insert it as new prospect.

But couldn't find the add this criteria in Pardot. Is it possible to do this? How can I add more criteria to update existing prospect or add a new one.
