Default origin on bottom center while adding using a hotkey

What really annoys me, is that the origin of some primitives is always in the center of the object. When placing a cube, cylinder, cone, etc. will be mostly be aligned to a floor like surface in my use cases.

When doing so I have to change it manually or use snapping tools to achieve my goal.

Of course changing this would break many things, so I could imagine a hotkey, i.e. holding shift while adding a primitive, setting it's origin to bottom center automatically.
