“Hi power “ mode

Is there a way to keep the watch in high power mode for more than ten seconds?  By this I mean the backlight setting just affects the light and not the update of the watch face.  I have a watch face the scrolls a lot of data and the backlight stays on for the setting that was selected, but the scrolling of data stops after ten seconds or so. You have to wrist gesture again to restart.  I’d like to set it to 20 sec or so but haven’t found anything.
