I can see what you're looking for, but since I use GSAK's note/log Section to enter my finds, run the Log cache macro, and then do a copy paste to get that exact info in to my FOUND Log for that cache, I don't see where bringing that same info back to gsak would help. (me at least)
When I'm dibe entering my finds in gsak and ready to post them to the web, I have a GSAK filter set to use the "date found by me" with the selection of 1 day, and have the "Found Status" set to just those caches found (uncheck the NOT FOUND Box) Thus, I can see what I did today, and post my finds from those.
Using the GSAK "date found by me" and setting it to a different day, I can quickly see what I did on that day as well.
All without the need to download "MY FINDS" at all. having said that, I do update gsak with the MY FINDS data weekly, sometimes though it's weakly. (no typo).
The thing I'm bringing back into GSAK is the log ID of my log. FindStatGen sorts by date and then log ID. Without a log ID the milestones are not in the correct order. The log ID is generated by GS, not GSAK.

My single find today was a newly hatched cache, which I found on the same day as it was posted. while I wasn't first to find, I was first to post. after posting, since there was no info in GSAK on the cache, and my find would have the same problem in the FindStatGen macro, so I went back to the waypoint URL and then clicked on the send GPX to update today's single find. Which I've also done with each find, when there's been several finds in a day. Not that I do 50-100 geocaches per day.
Edited.
