Support for Granular Text Style Linking (Individual Property Pickwhipping)

The Problem:

Currently, there is no way to link only specific character properties (like Font Face) between text layers without using complex expressions that overwrite everything else (Size, Color, Tracking).

When creating technical animations or "edutainment" content with many text layers, I often want all layers to share the same Font, but I need them to have different Sizes or Colors for visual hierarchy. Right now, using the .style expression is "all or nothing"—it forces every layer to look identical, or requires me to manually hard-code overrides for every single layer, which is a massive time-waster.

The Requested Feature:

I would like to see a "Pickwhip" or a dropdown menu in the Character Panel or Text Properties that allows us to:

1. Link Font Face only: Change the font on a "Master" layer and have all "Child" layers update their font while keeping their unique sizes.

2. Individual Property Access: Be able to use an expression like text.sourceText.style.font or text.sourceText.style.fillColor independently.

3. Style "Styles": A way to create a "Character Style" (similar to InDesign or Photoshop) that multiple layers can subscribe to within After Effects.
