Blender: Non-destructive texture edits

I’m wondering if it might be possible to allow for support for non-destructive texture edits in the Blender multi-exporter? Something like this, maybe enabled with another file chooser in the panel.

I know the workflow of base texture overrides is not the preferred workflow for livery authors, but is widely used (and necessary in some cases like Decals (Animated) Produce Duplicate Static Mesh Visuals . I’d prefer for my texture painting in such instances be a non-destructive workflow and assemble the modifications outside of Blender…

As is now, the shader config pictured does what I’m looking for, but gets tossed at file load when the shader config is rebuilt (by the plugin?)
