Custom footer text on client statements

I would like the option to add our company address and company registration to the bottom of customer statements. I believe that it is a requirement that this be on all documentation, but I could be mistaken? I also may have missed the settings to add this, if it has already been implemented.

We already have a provision to append footer text to the PDF output on sales invoices (see below), it would be fairly trivial to extend this to also output to client statements, would that work?
