Syncing leads by lead owner

Syncing leads by lead owner

Hello, 

I want to be able to sync leads by lead owner, as our CRM data contains data from two businesses that are split up by lead owner. However, when I try to do this the maximum number of criteria is 6, which is too low for my needs. Is there another way to sync data from only a select few lead owners? Or, perhaps, another workaround?

Thanks,
James
