Thanks for these great tutorial videos !!!
If the structure could include the audio track/s would be good.
If you look at JJazLab https://www.jjazzlab.com/en/download/
it uses freely available keyboard styles .sty, .prs, .sst, .bcs
https://www.jjazzlab.com/docs/jjazzlab_user_styles.zip
these are simply renamed to .mid (if RC could could import without rename it would be good)
they have midi markers for the different song sections
if RC could import the marker names into the Part names you could then easily build your song with the Structure Tool and still have all the controllers.
There are plenty of Styles, Style editors, creators and midi to STY tools.
