You know that's an option in the run uploading itself. If you look at mine you can see at the bottom it shows my splits using the same system. Plus when a run becomes obsolete there would be no reason to have it here so it'd be constant deletion of posts.
Yeah, I used to upload splits. Hitting at the end of every hole got annoying so I just time the entire run now. Once we get the 6th course out and start doing full game, I'll probably split between finishing and starting each course. (So 11 splits... or maybe just 6)
