Just guess-in here, likely your are talking about RealTracks. These are recordings so we only have what was recorded. In the early days there were no hold and shots recorded for individual chords, just rhythms and soloists. Then they started to records specific accents for some of the RTs. Even to this day not all RTs have accent recordings. And those taht do may not have all the chords recorded with all accents... Do you really need that #9 on that specific chord played as a hold? If so you may have to substitute a midi track where you can control each chord voicing and duration.

Or maybe someone else with offer a better suggestion.
