There is no such support in the code.

diff.c::run_external_diff() maitains and increments the counters
used to show the prompt in the form of a pair of environment
are used in git-difftool--helper::launch_merge_tool() when asking
you if you want to run the difftool backend on that 10th file out of
the 20 files.

Right now, you can only say Yes or No to that prompt, but it
shouldn't be too hard to add another choice to the response to the
prompt, saying "skip to 15th file", for example, and record that
"15" in a temporary file in $GIT_DIR/ and exit without running the
difftool backend on the 10th file, so that later invocation of the
git-difftool-helper script can skip without prompting you until it
is the turn for 15th file.

The launch_merge_tool() function needs to be modified in the
following way to do so:

 - At the beginning, see if $GIT_DIR/difftool-skip-to file exists.

   - If exists, read its contents.

   - See if the value is larger than $GIT_DIFF_PATH_COUNTER.  If so,
     just 'return' without doing anything else.

   - Remove that file (we are at the 15th path and done skipping).

 - Update the "Viewing .../ Launch?" prompt and offer another choice
   "Skip to?".

 - Update the if/then/fi statement that processes the answer to the
   prompt (right now, it takes n as a sign to skip the file).  When
   the user says "skip to 15th", create $GIT_DIR/difftool-skip-to
   file and record "15" in it and 'return'.
