Controlling scale via toggles/animations

I’m hoping someone else has figured this out, as it seems like it should be straightforward but I’m having a heck of a time finding any info on it.

I’d like to have a toggle on an avatar that can automatically set the scale of the avatar (as well as doing several other things at the same time). Everything else the toggle does is simple enough using VRCFury’s toggle component (swapping materials, tweaking blendshapes, etc), but the ‘Scale’ option doesn’t do anything (I assume it was meant for the days before we had the ability to easily scale from the menus).

I was hoping it might be as simple as having one of the scale-related avatar parameters set to the desired number (ScaleFactor specifically), but the documentation says those are all read-only.

And of course, yes, I know I could just activate my toggle and go manually change the avatar height, but I’m hoping to be able to bypass that part.

Has anyone managed this sort of thing?

Thanks~
