How to change MIDI out channel using playing technique text?

Hi Brian and other forum friends here.

Is this approach valid for playback of multiple instruments from the same staff, for example, the following case:

I have a violin staff in which the violin solo switches from arco to pizzicato and the sample library (EW) only has one key switch version for Legato/sus that doesn’t have pizzicato.
Or maybe this solution: Multiple sounds on one instrument.

Any help would be much appreciated.
