Yes, that's what I do as well. But it's a bit pointless as it doesn't come as a surprise to the applicant. The other option is to simulate an engine failure on a touch-and-go, at the same time telling ATC that you've changed your intention. But make sure that you won't screw up somebody else on the approach if you do that!
Current guidance for the Dual Training Flight is contained in AIC 127/1999 (White 378); it also spells out the admin requirements - which are limited solely to log book action.
I say again THERE IS NO FORM NEEDED for the Dual Training Flight!!
