A user inadvertently created & posted a number of Invoices with zero tax, and only discovered this days later.

Our invoices are currently 5 digits long. The client subsequently created about 40 new Invoices with just the tax charges, and manually numbered the Invoices 80214GST, 80215GST, etc. (This was so that their customers would know that this was a charge missing from the original Invoices # 80214, etc.)

The problem that we know face, is that we have 40 Invoices that always appear on the top of the Invoices tab, when we view the Enter Orders/Invoices/Credit Notes screen. (We have the Reverse order of order list selected as Yes in the Company Profile.)

Question: Is there a way to either renumber these Invoices, or remove (delete) these Invoices?

The client would really like to view the current Invoices in the correct position, while these 40 transactions are always appearing on the top of this screen.
