[RooFit] RooAbsMCStudyModule with more than one variable

Hi all,

is it possible to extend the RooAbsMCStudyModule module such that it takes more than one variable in the constructor, for the significance evaluation?

My problem is that I have an extended RooSimultaneous pdf, my signal variables are called Nsig_i, where i stands for the category index, and I would like to set the number of signal events equal to zero in each of this categories.

Thank you,
