It sounds like you may be talking about setting up some kind of persistent constraint that is enforced through subsequent operations?

That kind of persistent relationship would be quite difficult for me to set up right now.

This tool is a kind of "one shot" scaling mechanism, it does not set up a persistent constraint on an object, just does a direct edit of it.

However, it may be pretty easy for me to make a sub-set of what you are talking about (or maybe this even will directly fit what you want?), which would be to have "x", "y", and "z" variables available to the expression that you type in so that you could enter an expression like: 2 * x for the Y: value. That would edit the shape to have that proportion right then, but not set a persistent relationship. There should not be a problem with cycles since the expression is discarded and replaced by the evaluated numeric result as soon as you push enter.

I'll take a look at that.
