AMS - Always Print a specific color first?

I’m trying to use two colors in the AMS to embed text in objects (debossed then the gap filled in white - these are toys with the kid’s names on them for my daughter’s pre school graduation) and having trouble with the texture / quality of the finished objects. The text is there and legible but quite inconsistent and the surface is very rough.

I’m playing around with depth of emboss, seams, outer wall first - and making some headway.

However, it seems a remaining source of variability is the difference in whether the text or the shell is printed first.

Is there a way to have the AMS/Slicer always print white first or always print white last?
