No, because modification time is exactly that. Modification time, time the file was last modified, accessed. Breaking that could break all kind of things like automatic backup software et cetera. It would be a hack. Even more, every time another software accessed your file (even just to display the photo, or even rename or copy it in Explorer), modification time would be changed. Option in PM you mentioned "update creation time of photos with capture time during ingest..." should work, and Explorer should sort the photos right. I wouldn't ever sort by modification time unless it was something like work in progress versioning folder. I am on Mac, so I can't check it, but on Mac it works exactly like that - with the option set so, the creation time is the capture time, even in Finder (equivalent of windows Explorer)
