Unlink from B Line

I have figured out how to link to a b line, but I cannot unlink the node. How do I do this?

Select the BLine list that want to detach from the value node and right click select Convert -> BLine. this will turn it out to a independent non animated bline.
NOTE: you can’t do that with the Adavanced Outline Bline. It is always internally linked to a hidden BLine inside the layer. So the above instructions won’t be full valid
