As was mentioned on the Payment Entry page, there is a way to enter rent payments in batches as well
as changes to additional charges and future rents.
Take a look at this Batch Updates screen which is open to the Batch Payment Entries tab:
This allows the entry of tenant payments a building at a time.
There are also tabs for batch entries of Future Rents, Editing Existing Additional Charges, as well as
Adding New Additional Charges.
