You can use the script or the PLUGIN.
Generate New Style from Chords and Move to New Tab (Reaper)
VST 6 Multiple for more Bars (Reaper)
Regen Track Section Updating MIDI/RC (Reaper)
It's so easy, you can have the style change on the same track or another track to allow different FX and not have to automate them.
You can easily see the name of the instrument in the waveform with Write RT RD Names in items using Take Markers (Reaper) in the PLUGIN.
You don't need to worry about silence RT's as you can easily remove that section of track or mute it easy enough allowing it to be added if need be.
That's right. I intended to make the point it may be easier for someone familiar with a DAW to export like you mentioned and it's easier for them than using BIAB. Being faster and less complex isn't necessarily the best way for someone that is familiar and proficient with another program that yields the same results.
