Lock Dimensions of Objects

Is there a way/will there be a way to lock the dimensions of 3D modeled objects? We can currently lock sketch dimensions (so that two lines stay 1’ apart, and if I drag one it automatically moves the other), will we eventually be able to do this with the 3D objects themselves? So if I move one plane it’s corresponding plane moves with it, keeping their relation to one another the same.
