Short of exporting a wav file and adding your effect tracks with a DAW:
you could make a plugin trigger your effect samples and loop them etc. Such a plugin would need a stave to trigger his sounds.
If you don’t already have a sampler plugin of your own (I.E. Groove Agent, Halion 6, Kontakt, MPC Essentials, etc.), you could grab sforzando for free and make an sfz text file which would map your samples to MIDI Note events. Then you could treat your special effects as a kind of ‘drum kit’ and play them back with a stave in Dorico.
