Marketpress Order Numbers

Hi Guys,

Just a question really. Is the format of an order number fixed, and if so do you think it will ever be configurable?

Our accountant is asking for something like:
YYYYMMDD-ORDER NUMBER FOR THE DAY
i.e. 20110302-1

At the moment they are a 12 digit hex? and a bit hard on the eyes. I suspect there may be a good reason for it, so just wanted to understand the intention better.

Thanks!
