I'm using referenced master files for a bunch of football players, who are all similar build, but need different kit colours. I think I have it working using the 'unlink shared styles' option, but it does mean that the styles drop down list becomes fairly huge as each character has their own list of styles and it is harder to locate the right style to alter. Is there a way to add groups/folders to the styles list? It would be great if each character's styles appeared under a folder named after the character. I guess I'm thinking along the lines of maya's namespaces?
If I've missed an easy way to pick the right style please let me know too

One issue I'm getting - if I update the layer reference pointing to the master file, the styles revert back to the default colors, so if I need to change the rigging I have to start over with the color alterations in the animation file. That kind of breaks the setup - is there a way to update the layer reference while keeping the local color updates?
