Live components materials

When using the bifold patio door live component, all is great except the materials assignments.
There are 5 materials come with the component with name 0-4. I try to renaming them from for easy identifications (like Bifold Door Frame, etc) However every time I reconfigure the live component, new set of 5 materials are created w/ default attributes. So after running the live component configuration 4 times I get 20 materials in my model. Is there a better way to handle? thanks.
