With
SGC, I put a note right in the card holder 'instructing' them to only grade my
(miscut Bench RC) card as
'Authentic.' I also marked it as such on the submission form.
I have no connection to this guy, but found his short video basically describing the exact same thing for
PSA, so give it a look
(and try not to yawn as he goes on about Pokemon cards):
