Sagepay Order Reference number ID

Please can someone advise how to custome the Current Order ID to reflect your company name withe the concurrent numbering system of order numbers.
I am trying to combine a tracking of order numbers with the generated order number from my payment gateway.

Zen Cart numbering sysytem 1000, 1001 etc
I want to reflect our company - "company name" 1000 and so on!

Can this be done, as the current numbering system is not complimentary to my clothing store.

Without numerous complex edits, not in the current version, no.

In Zen Cart v2.0, currently in development, order IDs are very customizable. There's no ETA yet for the new version.

I have SagePay integrated into my shopping cart. When an order is generated SagePay creates an order using the reference number from the shopping cart e.g 123455-ANON.
How can i change the prefix ANON to my COMPANY NAME?
The numbering is fine that zen cart generates but my web developers have setup my shopping cart ID as my surname instead of my Company Name prefix?
can i use an admin portal within Zen Cart to change the custome ID name?:unsure:
