not simply, but it is possible.

For example d.nviz creates a script to do "create a view with a
oberserver at XXX YYY ZZZ ..." in a reproducable way. Studying that code
might help you write your own little script to set the shots up as
needed. Frankly I'm surprised no one has ever added these controls in to
a NVIZ panel yet, it's a common need and I'm guessing it wouldn't be too

AFAIK, the 6.2 branch defaults to on-screen rendering, and the bug is
only noticable in the devel branch where it attempts to do off-screen
rendering by default. Don't know if the on-screen rendering is
susceptible to overlapping windows corrupting the snapshot or if double-
buffering has been implemented to avoid that.
