How to get a real random pick of cards ?

Sorry for my english, non native speaker here. I hope to be clear enough in my explanations.

Is there a way to have a custom training session with N random cards of a pack without considering your current learning rules ?

To be more specific : when I try to start a custom study with 200 random cards, I always have my due cards put first in the "random" deck.

Is it possible to have a one-shot study of N true random cards with no study rules applied whatsoever ?
