Combining Note Performer and Other VST

Does Anyone know if you can combine Note performer with other VST?
SInce Note performer is expression Mapping, I was wondering if you could use some other sounds using note performer?
I am not sure if this is even possible

It’s a pain, do a search. One way is to set NP in an endpoint config of its own, then combine that with another in a playback template. Then it will populate the mixer
