Hello there, edna8.
We're unable to edit multiple invoices by batch. You'll want to edit each invoice and you can use the recent transaction option at the upper-left corner (counterclockwise icon) of the screen after you click Save.
For more details on how to manage our sales transactions, you can use these pages:
Let me know if you have other questions. Take care!
You may export the Invoice data out, modify it, and import them back in bulk.
