Free Move Bone On Rigged Object

There is probably a simple solution to t$$anonymous$$s but I've always dealt with animations rather than what I'm about to mention, but still, the first time I asked a question on here, I was all, "Why are color values getting weird between 0 and 255," not realizing the values are 0 to 1.

Anyhoo, that was five years ago, SO what I'm wondering is t$$anonymous$$s:

Let's say I have a pole. That pole is rigged with one bone at the top and one at the bottom. Without using scale, how can I free-transform one of those bones and cause the pole to stretch? Seems like the bones are always locked and are only affected by scale and rotation.

What I'm doing is creating a dynamic system where I can make a control arm on a ve$$anonymous$$cle's suspension system longer or shorter and I need the user to be able to configure that.

If any of t$$anonymous$$s is unclear, feel free to ask questions. Remember, I don't want to use bone scaling for t$$anonymous$$s because that seems non-intuitive.

Thanks!
