Creating editable primitive shapes in edit-mode in scene view

Hey,

I need to draw primitive shapes (with only their wireframe) in the scene view in edit-mode and I need to be able to edit the transform of those shapes. Basically I want to draw a wire cube for example, and I want to be move/scale/rotate it much like if I were to create just a cube mesh. How can achieve this, do I just draw a cube using drawgizmo and then do something with handles so that I can move those cubes? I'm not looking for any code or something, just maybe a script reference or a method of how I could achieve this.

Thanks

Alex
