Context
I have to import a large list of contacts. Data for each contact includes name, a national ID number (unique), email, etc.
When I use the import function, there is no way to detect which contacts already exist, so they are duplicated.
Question
Is there a way to detect if a contact is going to be duplicated so I can skip that one and go to the next one?
I know there is a "fuse" function, and I already use it. But this is "after the fact", and I want to avoid the creation of duplicate contatcs.
Thanks!
