Using PrusaSlicer, is there a way of getting a thicker (two layers, preferably) support base? See linked pic for what I mean.

I find that I spend too much time ensuring that I get every speck of support material off the print plate long after I've removed the actual print.

When it comes to the skirt, I always set it to be two layers tall for this exact reason, and I was hoping it's possible to do the same with the support base.
