Idea to make creating movable structures easier

As of right now, it is nearly impossible to move a created structure in one piece. Pistons only move the blocks directly touching it and the blocks behind that. This result to structures becoming deformed as movement occurs, making the endeavor pointless. My proposed solution to this is the addition of a "glue", which would be applied to the sides of blocks and would result in the attached block (or blocks if the proposed item is applied to multiple connecting blocks) moving as one with the first when pushed by a piston.
