Unapproved bill issues

SUGGESTED

Looking for help on how to rerun a bill. Steps taken:

Client had two time entries. 

Ran bill, discovered error, undid, and cleared (instead of revised) bill.

Time entries still show as billed, bill remains in billing history, and shows up in the list of reprintable bills.

I want to re-run the bill using the same invoice number.

If I delete the two time entries and re-enter them, then run a new bill, will the same invoice number be used?
