Hi @rraby, it was discussed in the past.
Here a possible workaround suggestion (for the playback, in a similar case):
Edit:
Basically you can insert a duplicate instrument in the same position in you kit (in my example a snare 2), then add the note that correspond to the accented note to it, apply the accent on it (selecting it in play mode), hide its stem, set the voice column index to 0 for all the notes (to make the notes overlap), remove the rests, and you have your accented note (I exaggerated the accent velocity in my example):
Result playback:
Dorico file example:
