Currently it's not.

The problem with this is that you must be very selective with what you
generate sgf traces for. If you tried to do something like that for an
entire genmove (for technical reasons you can't, but let's ignore
that) of average complexity you would be completely drowned in
variations and get a huge sgf file which would probably crash your sgf
viewer or at least render it useless.

This has been discussed before and I'm strongly against it. One reason
is that we want to have external sgf files for the regressions because
it allows them to be examined by other tools (sgf viewers) and other
GNU Go modes. But most importantly I want to keep the GTP protocol
simple and easy to inspect. Inline sgf would not be a development in
the right direction.

The answer is to use native GTP commands to set up the position.
