nanoDLP

So this is a feature that I have seen on FDM slicers and would come in handy with nanoDLP.

Some models have flat surfaces...(I tend to print these directly on the bed so waiting for the erode burnin layers but this is a different feature)
...some of these so call flat surfaces are not totally flat...maybe the were drawn by hand
or maybe they are on supports but the support program failed to make the bottom of the supports totally flat.
Whatever the cause the result is things do not adhere well in the first few layers.

The new overhang coloring in Nano makes this even more clear.

I have a model that is on supports and it looks like the supports are all flat on the bottom and in the same plane
but if you zoom in they are not perfect....so my first few slices have almost no contact area.

what I would like is when adding a model, and not using the support option, to be able to drop the print
by some small amount..basically sheer off the botton to make it flat....this could be done by skipping the first couple
layers or merging them or something.  This would of course be an option and only used in specific cases were some
small surface feature or bump is not to be printed.
