Sales Invoice

HOw can I indicate on the reporting part of the invoices; and I’d like to include that; 1) Report Person doing the invoice, Person Authorizing the Invoice

and if that can include the remarks just above the persons writing the invoice and Person Authorizing it?

Do all this with custom fields.
