Faces on same object using different shaders

I'm trying to do something that is quite common practice in 3d software as long as I can remember (15+ years experience)..simply use two or more different shaders for one object. For example I'd like to have one object with one or several faces using the first shader/texture and then the rest of the faces using another shader/texture. I don't need these to tile or layer, or anything fancy. It seems substance painter only allows one shader per mesh? Or am I missing a checkbox / option?
