2 Questions

1) First off, I want to make sure I uploaded my CSV correctly. When I uploaded about 19,000 contacts / organizations from a Zoom Info CSV, I uploaded them as Contacts. Should they have been uploaded as leads?

2) How do I bulk assign contacts / leads to certain sales reps? Their territories are assigned by city and I have a field mapped for cities already so just need to know how bulk assign them to certain reps
