Moving a workout

I've done a few workouts that started at ~11:30 and went over midnight and while the Garmin shows the date I started, the BT uploader puts it in the following day (or the day it ended). Not conventional, but I can see maybe doing some 12-1am workouts in the future anyway that I would still want to count on that day rather than the following. 

So would it be possible to get an option to move a workout (and all the data) to a different date? I can see it being useful for those making typos and really just changing the date field shouldn't be too complicated?

Love the site, thanks!!
