Ability to "lie" about required instrumentation

Some sympathy for us organists! A fairly easy one, I would imagine.

Given that the entire model of organ architecture is at odds with the MIDI model of this and all music-editing applications, those attempting to credibly produce organ music, or write new compositions for organ, with MuseScore have to decide between two options: (1) Write the staves and notes as they appear in professional, standard organ music, and assign to the staves varying voices chosen from flutes and reeds on MuseScore that add up to a credible sound-set (2) Choose "organ", lose the ability to control contrasting sounds, or control registration or sound in any way, suffer the "short notes kill long notes" "feature", and lose the ability to perform any music not suitable for a very loud, if beautiful, plenum with 16' (there certainly is much music suitable for this sound, but not even all rock music is fortissimo).

The only reason, other than ignorance and laziness, why someone might choose (2), is so that someone searching for "organ music" finds the work, whose instrument is listed as "organ". If you do not care at all what it sounds like online, or are a truly fundamentalist believer in "MuseScore is a score preparation program; if you don't like its performance skills, use something else", perhaps this is adequate. But I suspect that even among the people who print scores from MuseScore (especially from the site) to play them on physical instruments, every single one first clicks "Play" to see what it sounds like.

Here is a movement I just prepared, with some care to simulate credible organ registrations, including mutation stops, https://musescore.com/user/1831606/scores/1361021 , which is listed as "recorder music" because I used/abused "recorder" to produce very credible organ flue sounds. It is listed as an arrangement for recorder; it is not. It is an organ score. I would like the ability to assert precisely that searchably.

The organ continues to play a mighty important role in the history of Western Music. Given that real support of organ music in MuseScore is not at all in sight, this little proposed feature would help a great deal. It would help others who find one or another sound inadequate (e.g., oboe for the slow-starting English horn) and would like to divorce MIDI instrument choice from "real instrument" cataloguing of the score.
