Can we change raster engraving to go top-down, to avoid smoke discoloration?

Not sure if this really belongs in Q&A, but it is a Q looking for an A, so… I’m trying to figure out why the Glowforge etches raster images bottom-up instead of top-down. Or if there’s some way I can make it go top-down. My reason is pretty simple… smoke damage. The air-assist sits above (y plane, not z) the head. As such, it blows the smoke straight down as the machine etches. Therefore, as it’s etching, all of the smoke hits the areas you’ve already etched. Where if it went down instead…
