Clear old payables/receivables

It would be really nice if there was an option to clear old payables or receivables in the next fiscal. Often the accountants post entries on the GJ that don't jive with current payables or receivables so I have outstanding from years back and no way to easily clear them. i.e. my GST return on AGExpert is never the exact amounts that are filed by the accountants so are never completely cleared in next fiscal.....and you can't adjust a GST return as the transaction is always locked out. Some method to address this in the future (so outstanding amounts don't show up on new reports) would be fantastic.
