KC868-D8 V4.37 new firmware update

Great improvement, thank you.
Just one question about the buttons. If I press the button once, the dimmer value is 100%. Is it possible to get an update for the following use case:

1. I dim my lights to a certain value e.g. 50% (holding the button accordingly)
   
2. Turn it off by pressing the button once
   
3. Turn it on by pressing the button once again
   

My expectation: The dim value should be again at 50%.
It is the same as the "remember the last state", but just for pressing a button.
