v11 bitmap color art painting

Just starting to play around with Harmony 11. Great upgrade.
I want to create a drawing that uses vector line art and bitmap color art. Is there no way to send the vector stroke to the color art layer so that I can fill using the paint bucket tool? The tips just show the bitmap color art being filled in by hand which can take a lot of time. I want to lay down a base color using the paintbucket tool and then work on top of that with the bitmap brushes. You can send bitmap line art to the bitmap color art layer, why can’t the same be accomplished with vector line art?

Art layers can be converted to either type after creation, so my problem can be solved by making a layer using vector for both line and color art layers, doing a paint bucket fill on the color art layer and then converting that to bitmap.
