Can you do a plumb cut with a Fascia sweep?

[hdjohnson]

I have a typical gable end roof and I want to apply a 1x10 fascia board that is plumb cut. Is it possible to do a two-cut plumb rafter cut on a fascia board? If not, how can you handle this without doing another roof?

An inplace extrusion or sweep would be one way.
