you are mistaking, it is not possible in hardware and software on the Yocto v1, there's is only global accent, that can be triggered by a single note, but it's still global

the yocto v2 does have individual accents if thats your thing

About the global accent, it could be nice to be able to still trigger it as in fact it can already be assigned to a note.

You're right about the per-voice accent, but for a very annoying reason. I will fix the manual accordingly.

The Yocto hardware, like the original 808, doesn't support per-voice accent on paper. Normally, the Yocto plays a step by triggering every drum voice that's programmed for that step at precisely the same time. In expander mode, each drum voice cannot be played at exactly the same moment. MIDI data is serial, so the notes / messages do not and cannot arrive all at the same time. Even if your MIDI sequencer is telling the Yocto to play the bass drum and hand clap together on the first step, the Yocto will not play those voices at exactly the same time. The bass drum will play first, and then the hand clap will play (or vice verse). The minimum time between notes arriving at the Yocto over the MIDI cable (~1ms) is similar to the duration of the trigger pulse in the Yocto (~1ms). This means that you can accent the bass drum hit and not the clap hit for example because the two hits will not sound at the same time.

This is also why the global accent does not work in expander mode. The accent is "over" by the time the next note arrives at the Yocto!
