Block direction controlling thingy

You know that annoying moment when you have to move around just to make a piston face in the correct direction? I would like to suggest a command that makes it easier for people place diretional blocks easier.

E.g /blockface down - Makes all the blocks you place face downward /blockface up - Makes all the blocks you place face up /blockface north - Makes all the blocks you place face north
