Stacking midi channels in one instrument/voice for export

Hi, I’m wondering if it’s possible to export a instrument on one track with two midi channels stacked superimposed. I use the bbcso and the staccato combined with long articulation, this is nice for fast passages that need a rhythmic and lively pizazz. (I need these on separate instances not shift clicked on one) I then go into a daw and adjust the velocity of these channels to get a decent mix. This isn’t a big deal because I can do this in a daw at a decent speed, but it’d be nice to know for the future if I could do this in Dorico.

Thanks
