Even though I don't know if it is or isn't possible, I don't think
that it should be possible and the reason is the mechanism
Interchange has that prevents a malicious and unauthorized visitor
from altering or deleting data.
The mechanism for updating (or deleting) records from a database
using a form makes use of a scratch variable to effectively say
whether it's okay or not to make the change. If you could set scratch
variables through a URL (or a POST method also) it would mean anybody in
the world could write whatever they like to your database just by
entering a properly crafted URL. It would defeat any mechanism you
have in place that verifies the authorization of the current visitor.
