ability to pick up non vehicle objects with newly added "walk mode"

To elaborate, being able to pick up objects when close enough to it, say 6 feet, by the press of a button, when the button is pressed the object being picked up gets locked with the camera so it moves with you as you walk, press the same button to drop the object, this would help with loading stuff into vehicles, like loading a haybale or a rock into the pickup, sure being able to pick up a multi ton boulder or bundle of lumber isnt realistic but why the hell not
