Using BDT to classify more than 2 categories (the usual background/signal)

Dear all,

I am new in using ROOT and TMVA and I have a generic question about what is possible to do with theses tools.

I am interested in using a BDT (and maybe rectangular cuts) to separate my data in more than 2 categories (the usual been background versus signal). Is it already implemented ?

Thank you for your time,
Cheers,
Jordan
