Is there a way to keep screen on (not background light) in the battery saver mode?

I usually keep the watch at battery saver mode to have longer battery life. But I like to take a peek the time constantly and I really don’t want to touch the screen first before I can see the time.  

Is there a way to keep the screen on at battery saver mode?

I notice that if in the Normal mode and Running mode, there is a option to choose if I want to keep screen on or not. But in battery saver mode, there is no option to change. 

I understand that screen on will decrease battery life, but please give me this option so at least I can choose.
