I've been wondering about the same, Bill. Haven't really pursued the
matter, but I suspect that there must be some software designed for
astrophoto that can do it.

Subject: Noise reduction
The lightning thread got me thinking.
In camera noise reduction is done by doing a dark field exposure,
and using that as a template for removing noise from the image
exposure.
I am wondering if anyone has tried doing this as an out of camera
operation?
If it were possible, it would remove one of the problems with in
camera noise reduction, which is the loss of camera functions while
noise reduction is being calculated.
