Agreed, this is extremely frustrating.  I have payroll journal entries coded like PR2021-01-02, and intercompany entries like IC2021-01-02.  Then Bill.com syncs that night and I get 50 entries of PR2021....I shouldn't have to go in and change each one individually, which is also difficult because it's unclear sometimes to tell which ones are correct without opening each entry. 

Truly a time-sucking and frustrating problem.
