There is a review suggestion to consider setting up direct deposit on the T1DD form, but this shows on all even if they are already signed up and we have never competed the form.
I think it would be more useful if the review mark was linked to the Client Data enquiry (CDR) response and the question - Signed up to Direct Deposit? with No as the answer. Then we would be prompted to suggest signing up on the clients the CRA doesn’t already have with DD.
