Original Button/Slider_moves in BTT?

I love much more original touchbar Brightness and Volume Buttons that after touch work as sliders. But not find way to create button and after touch moves - make slider activity..
Its not possible?

Why I ask - this button/slider original variant have smaller working space in touchbar and its good.
May be possible to rewrite GUI elements of Original macOS touchbar Brightness/Volume (not like big icons, grey background and big space)
