Label parts in BBM?

Do you have plans to allow part labeling in BBM? It would be really nice to be able to label the parts in songs with more than 2 parts so organization in BBM would be more intuitive. For example: V, C, V, C, B, C. Maybe you allow that and I just haven’t figured it out.

Also, along the same lines, it would be nice to be able to duplicate all of the components of a song’s part for easy song management in BBM.
