Multiple biasing operators attached to a single logical volume

The current GB examples do a great job of showing how to set up biasing for certain situations and how to extend it to other situations, but they don’t do a great job illustrating how multiple biasing operators could potentially be used together. In my case I am interested in a combination of forced interaction (GB02), brem splitting (GB04), and importance splitting (GB06). I currently have all three set up to work independently, and they even work together if I assign them to different logical volumes, but what can I do if I want more than one of them to occur in the same logical volume? Is this what parallel volumes are used for?
