Single quiz with two short codes?

Hi,

Is there a way to show up random questions from two different quiz into same short code? For example – if i have a master list of questions under [mtouchquiz 1], and then some new addition under [mtouchquiz 2], can i combine short codes so that it can pick random questions from both quiz questions database together?

I tried [mtouchquiz 1,2] but not success. I can only add quiz 2 questions to 1, however I would like to create one quiz per state, and so then I will have to copy master quiz 1 to each 50 state quiz and that’s too much manual work so wanted to see how I can merge two quiz into one single short code so that I can serve up master quiz and state quiz questions into one single quiz.

Can someone please help me with this hack? or feel free to suggest the best way achieve this.

Thanks.
