Extended import functions?


New Member
Hello guys, I want to ask does MailWizz has some extended functions / addons for importing contacts? I mean exactly 2 importants things:
1) Replace/Not replace old data with new data? For ie. in interspire there is a function: yes|no "If email exists replace the old data with the new imported file?"
2) Also Mapping of qustom fields with the headers of csv file.

Thank you in advance!
