Subclips archived copy entire source footage (ghastly huge!)

In the preplan stage of my editing, I’d go through the footage in the “Source” monitor of Premiere Pro, then select (I)n and (O)ut points of something I liked, then make a “Subclip” of that selection.  The pop-up box has a checkbox (which I tick) to “Restrict Trims to Subclip Boundaries.”  The subclip(s) would then be in the media files of the PP project for my forthcoming editing.  Days later, when I’m done with the project, I archive everything to a separate drive, using Premiere Pro’s File/Project Manager “Collect Files and Copy to New Location.”  The danged thing copies the media, yes, but it re-copies the entire raw footage for every subclip I made from that raw footage.  So, in this example, the raw footage is 14GB, and I made 22 subclips.  14x22=308 gigs. 

Why doesn’t Premiere Pro have subclips as a coded reference to the original raw footage instead of currently pulling in the raw footage each time a subclip is made?  I swear (or maybe it's the THC gummies talking) that in earlier versions of PP, the “Make Subclip” had an option to include or not include the entire raw footage as part of the subclip.   If it didn’t, it should.  And yes, I did tick “Exclude Unused Clips” in the Project Manager.

Still hoping there's a better way to make and archive subclips as I described above on May 11 of this year.  I've attached a screen capture of the PC File Explorer list showing each subclip that was created when I used the Project Manager "Collect files...."  Again, each subclip is archived as the entire source/raw footage, regardless of the subclip length (in this case, the raw footage was a non-stop 45 minute interview; which I made subclips of when prepping for the edit).
