Linking accent dynamics to playback dynamics in drumline scores

It's common in drumline music to have passages with two dynamic markings-- one for accented notes and another for unaccented notes. For example, in my screenshot, ff/mp means play the accented notes at ff and the unaccented ones at mp until otherwise noted. The playback though doesn't reflect these dynamics outside of the first two notes. After that, played back sounds like one dynamic for the remainder of the passage.

It would be nice if there was native drumline support for "All accented notes are ff" and "all unaccented notes are mp" and have the playback actually reflect those dynamics. I don't think there's a way to do this currently.

Thanks!
