I'm working on a prop that is composed of five total props: a base, and four smart props. The base contains morphs for changing both its width and its height, and the smart props do not follow these morphs. They do follow the x, z, and y scales, but that's not what I want.

Is it possible to get these smart props to follow these morphs? I was thinking about a master parameter on the base to control both the x and y position of the smart props, or linking the existing morph dials on the base to such a thing.
