Direct drive motor speed control question

Evening all, I am going to play a trick on a friend who says he can pick a direct drive turntable blindfolded.

I have disguised a cheap Stanton DD but there is one giveaway I need help with. It’s the instant start up - is there a way to ramp the speed up somehow? I know this is usually considered a feature of DD turntables but for this scenario it isn’t.
Regards, sp
