I'm relative new to FusionAuth but it's quite a good system so far. Only I can't seem to do is import users correctly with my current setup. The setup is that I don't know from an N amount of import files which are all ready in imported. So it could be when I call
Import users that the email and/or username is all ready present and the whole import is canceled. This is now ideal for me, I really would like to just skip the ones that are already present.

Does anyone have an idea to do this? Would it make sense to first query the API to know which of the usernames and e-mails are present.
