How to save multiple-sprite sheet parameters?

Hello, I’m currently working on a project, using the new 2D sprite system. I have a image that contains all the characters body parts ready for joint-pivot type animation.

Every now and then I want to touch up some things my character like color, shape etc. I was wondering if there’s an easy workflow to swap out the image and retain all the pivot settings. So far I’ve just been swapping out the image file in the project folder. Recently I’ve been wanting to change that file to a .PSD file making it even easier for me to make changes. But I can’t seem to find a way to copy and paste the parameters of the sprite editor. Pivots, position, name etc.

Copy the multiplesprite .meta file of your base image and rename in explore with other sprite names.
