Can 1 user have multiple IP addresses for different domains

I migrated from cPanel, where a user controlling multiple domains is called a "reseller." I thought putting all my domains under the "admin" account would be one user (admin) with less than 10 domains, and I would qualify for the personal license. Now almost everything I try to do is rejected because I have 9/1 available users. I'm not sure if this is fixable--I do need different domains on different IP's. But IP's are assigned to resellers, not users, and it looks like each user gets only one IP.

Is there a way to give a user more than one IP?
