UV Galvo Flood Fill-forcing same direction

When using flood fill on a galvo, the detail this setting can produce on small features is astounding but the finish is something that needs help.
Currently, an object fills in most of the object in one direction and then comes back in another direction to complete the job. That change in direction leaves a wonky finish.
I would like flood fill to maintain the same direction for the entire object.
If there is a workaround I’d love to hear about your approach.
Otherwise, I’d love to see this included in a future patch.
