Sending polyphonic note information to sampler

I’m struggling to work out how to send polyphonic note information (chords) from the MIDI router to a sampler to trigger individual samples as chords. The only method I have found is to create a single instance of both the sample and MIDI router in scale mode and group all instances. This seems very tedious, especially if you want to create long chord progressions.

I am aware you can record chord progressions as audio in a DAW and chuck in the samples from there, but is there a way to create a chord using a single instance of the MIDI router and send it to the sampler?

Any help would be much appreciated.
