The functionality to import Payroll Posting Accounts in v2016 seemed like a great addition. That is until I found out that you have to export out all your existing payroll posting accounts, add the new ones to the existing list, and then re-import them all back in. We have roughly 3,700 payroll posting accounts and could be processing checks on any given day, during which time, I do not want to mess with the existing payroll posting accounts. An improvement to this functionality would be the ability to add/append to the existing payroll posting accounts, not just override/replace.
