I could swear this used to be a thing...

MacOS Sequoia 15.1.1, AE 25.0.1

Say I have a 200x100 jpg in a 1080p comp. Then I precompose that picture. The bounding box is now the size of the comp with the anchor point at 960x540. I could SWEAR that when I turned on collapse transformations and the bounding box shifted to the size of the jpg, I could then auto center the anchor point to that bounding box. It no longer does that. I even reinstalled earlier versions of AE and still, no.

Did I maybe use a plug in to do this? Did I dream that I did this?

In case someone can think of an alternate solution, my problem is that I have 300 pictures of varying sizes in a 1080p comp that I used Pastiche to arrange into a specific shape with specific sizing. Then I precomposed each individual image so they would all be at 100% scale in order to use one expression that scaled them up based on a luma matte. This workflow is only efficient if I could easily auto center the anchor points of each precomp.

Hoping the community can prevail,
