Keep Touch Panel glowing when the lamp is off?


I’m using Bedside Lamp for quite a bit of time, but cant find an option for keeping Touch Panel glowing when the lamp is off.
Very handy feature, imo, if you are trying to turn on lights in complete darkness (without bright-as-the-sun screen of your phone, obviously).

There is an option “Touch Panel light auto off” for keeping it dark when the lamp is ON, so, seems like panel has its own LED, which can be controlled separately.

Is there any way to keep touch panel glowing?
Or can we request such feature for nearest firmware update?
