Bank details to display on SI and Statements automatically

For clients who issue SI's (and presumably customer statements) could there be automation for the bank details to be displayed on the SI and Statements. These layouts would have a footer with some default text already embedded and then 'look' at the bank account details held within the banks. On the SI the bank that receipt will be made into will be assumed as the default bank account however the user could change the bank account at point of entry (and would user trader defaults to assist with this step). For clients who use more than one bank account, this saves the creation of multiple sales invoice layouts and, crucially, allows them an automated approach to raising + issuing SI's and Statements with the correct bank details enclosed.
