how to see all the subclips (in/out points) into the same main video

Why doesn't the Source monitor show all three subclips out of the main? Because the metadata for those subclips is stored as data for the subclip not the original full clip. Every item shown as an individual item in a bin has its own meta storage. The original clip has its data. Each subclip has its own, separate data.

I understand what you'd like to see, but the way PrPro stores meta, it ain't gonna happen.

Subclips "technically" are where you've selected a section of a longer clip, and right-click "create subclip", and given it a name.

If you do, those are stored as separate named items in the bin.

If you simply mark in/out and drop to a sequence, then move on for another in/out point, you haven't actually created a specific "subclip".
