I don't think you can. Unless you use tablet as a just pointing device not as a tablet (with menu picks and stuff).
I've asked that question when I went to ProE training, about 5 years ago, to one of the PTC guy.
And he thought it was a bad idea, you don't need it.
Then I thought to my self, 'This guy never worked as a draftsman or designer.'
I think it is a good idea to use tablet. I still use it for my 2-D CAD system.
