IS there no drop to bed feature for negative space/modifiers?

Hi,
Anyone have any idea how to accomplish what im after in the vid below?
vid of issue

I think the only way is to unassemble it to make it drop, then reassemble it. Otherwise, you can move the individual parts with the move command while still assembled

Yeah ive found some work arounds like that but for certain projects its a huge pain! Gonna have to add this to upgragde suggestions because i cant be the only one in need of such s simple function. Very disappointed bambu dont have this already.
