Field for complete invoice number

Hello,

Our client has an eshop since january of this year. He is using your plugin to generate and send the invoices to customers.

Now he would like to send these invoice to his accounting software.
The problem is, numbering of invoices are skipped. Numbering goes like 1, 11, 4, 7, 10,…

We found out that we can read actual created invoice number from field _bewpi_invoice_number but it is without sufix and prefix.

My question is:
Is there a field created by your plugin for complete invoice number which was actualy sent to customer (with sufix and prefix included)?

There are 500 invoices so we need to find some clever solution how to get these invoices to accounting sw.

Thank you for you help.
