You can certainly draw again from the same question bank. However, there's no setting to indicate you want the second draw to include some previously answered and some new questions. Random selection is random (though you can indicate that certain questions should always be included).

P.S. I recommend that you post questions that are specifically about Storyline in the Storyline section of the Forum: Articulate Storyline Discussion Forum - E-Learning Heroes
