Hello, I have a requirement for Spine Dress Up within Flutter, which involves replacing parts in Spine with scattered images from outside the Spine atlas. In the Dress Up feature of the example project from spine_flutter, it seems to only support swapping sprites within the atlas and doesn't appear to support replacing with external sprites. How can I use external scattered images to overlay corresponding parts in Spine? This is akin to how in the Spine example project within the Unity engine, SpineBoy can change glasses and weapons.
