Remap Brush Tool

It’s been 10 months since my last post so im wondering if Aseprite has added this functionality or if there’s now a script that allows me to remap multiple colors of sprites to a different color per sprite on a sheet.

Use case being to remap different body parts of a sprite to create outfits through pals. The body parts don’t have separate layers as I created this sheet using spritesheeter.

Here’s a video showing this in another program:
