Pdc does not retain timestamps of files when copying them from source to pdx

I'm trying to optimize my workflow by speeding up data transfers to device using unix's rsync. See https://devforum.play.date/t/installing-pdx-files-on-hardware-from-the-command-line-with-macos/8750/3

rsync's optimization strategy of only transferring changed files is defeated by all files having their modified timestamps updated to the current time when pdc copies them from the source folder to the pdx. This includes the chunky ones that slows our transfer down, like mp3's and pdv.

Could this be fixed? This could also be used to improve the transfer speed of uploading from the simulator, where the same issue is seen.
