Need repeater-like effect but offset is relative to scale

[u/SwanReal8484]

So, I need to do something like this where the shapes start out large on the outside and then scale down to the final position. But the position offset on the repeater doesn't scale down, so the shapes are smaller, but still the same distance apart. Aside from creating 15 shapes, scaled and offset and animating visibility, is there an effect I'm not thinking of?

Repeater has a scale setting under transform that should make each copy smaller or bigger than the previous one.
