How is this not a thing yet? This has come up multiple times in the past 2 years. Implementation cannot be that difficult, all the pieces are already there. Just let us pick an extruder for dense support layers. This would make PVA support SO EASY.

This idea would make dissolvable support so much easier to use! and It would be easy to implement! Just a separate extruder select for dense support layers. This could also be used to reduce the number of tool changes required when using PETG and PLA, or Ive even heard of people doing ABS and PLA.
So many times Ive remembered too late that S3d doesn't have this basic function and had to go save a separate mirrored file in sketchup. Makes me grumble every-time. MS paint has this.
The new interface layer settings for support material is great! This would be a great feature to add to infill as well. No changes would be needed that I can think of.
