I had a call back from the Profile team, my query got moved up the ladder as they have asked for my data from the help menu.  I will let you know if they offer a solution in the next couple of days.  Something with that last update got left behind!

For the T183, AUT-01 and Business Consent, I do up a dummy return with no name or SIN, then print each page as a one page print to pdf, and just send out the pdf to everyone, asking to return to me via regular email, Print their name, NO SIN, $$$ amounts, or address, sign the bottom, all good.  My information is on the forms.  I do it year year to get the new tax year on the top of the form.  The CRA has accepted these from me as being valid.
