I'd like the ability to disable trusted sender (thereby having to download and send an article to the patron manually) for specific transactions or specific patrons, not just specific lenders. Disabling trusted sender at the TN level would help for cases where the patron has specifically requested a color/high resolution/accessible copy. I prefer to review these files before having them reach the patron so they don't feel like their request was ignored if the message was missed by the lender.

I think being able to disable trusted sender at the patron level would help smooth relationships with patrons who are known to be critical and particular; in these cases I would want to verify the article no matter the trust level with the other library.
