I think this is the tool you’re asking for, made by Ledger: https://forum.renoise.com/t/new-tool-2-8-3-1-reorder-notes-by-pitch/39315
Some time ago, I prove the tool of Ledger in R3.0.1. It seems to have errors in the code or lack more code, which eliminates some parameters and also does not work with the Notes-OFFs. FFX commented the ruling a year ago.Ledger said it will review, but the thread was dead.
If you play live with a keyboard, the pattern is full of Note-OFFs.It would be necessary to use more columns for not overlap each note durations, in the conversion.
For me, the two tools would be very useful if they work perfect. Both Ledger tool, such as sort notes per octaves have failures (Note-OFFs, lost parameters,and things like that). It is a pity they have not been completed…
