First Name / Name on Documents

What a great system FA is - Well done and congrats to the developers!

I have a minor question but couldn't find any solution in the forum so far. Does anyone know how to display First Name and then Name in Billing/Delivery addresses on reports (Sales Orders, Invoices, etc) rather than Name / First Name?

It's not a major but if there is a simple way to achieve this I would very much appreciate your help!

Cheers! Carlo
