Any way to increase the display timeout time past 15 seconds?

Anyway to increase the display timeout time in any mode to say 30 seconds? There are occasions for me that I just need to time something in the 15ish second range and I find it annoying that the watch display shuts off, or if I use always on mode that the second hand disappears just as I'm coming to a close timing. Unfortunately, so far I often just forget to move my wrist, or don't quite move it enough to extend the timer.
