Is group editing via midi item possible this way too?

[Triode]

I like the idea of editing audio using a midi item on a folder. A bit like this thread: https://forum.cockos.com/showthread.php?t=205731
But not using item groups

I'm wondering if it's possible to modify SPK77's script below slightly to add the "folder item" functionality in - using the SWS select children and parent tracks commands in the script and setting the folder track to record a midi item while the child tracks are recording audio.

At the moment the script selects all the items on the folder's child tracks to a depth of one folder (I have it set as the default click). If the parent track's items were always selected as well (while the child track's items are also selected in the case of clicking on the folder item) it would add to that scripts functionality.

I really like the idea of editing takes looking at the wave file of the composite audio of the whole folder - Especially if it was reliable enough to be able to collapse the folder and still affect the contained audio!

while(is_child_track == 0 && i < tr_c) (
  track = GetTrack(0, i);
  depth_change = GetMediaTrackInfo_Value(track, "I_FOLDERDEPTH");
  cur_depth += depth_change;
  track == last_touched_track && depth_change <= 0 && cur_depth >= 0 ? is_child_track = 1;
  cur_depth == 0 && depth_change == 0 ? is_child_track = 0;
  i += 1;
);
