Amending Generic text on Statement header

Hello R E M Freight Ltd, 

Welcome to the Community page, 

This is not possible to do In Quickbooks unfortunately, you can leave it as feedback within the main cogwheel, which gets sent straight to the developers. 

Good luck with that, I have been complaining abut that issue for over twelve months. We do however, have a new, slightly more complex  procedure for logging into the application. Woopee!
