Individual Percussion Instrument in Kit Routing

Hello!

I can’t for the life of me figure out how to route individual percussion instruments within a kit to specific VST instruments. In Dorico 3.5, each individual instrument from a percussion kit had its own track, so I could assign them to whichever VST instrument, port, and channel I wanted. In Dorico 4.2, all I seem to be able to access in the Track Inspector is the kit itself - how can I access and route specific instruments in the new Play mode?

Thanks for the help!
