Bruce, I haven't used tksurfer before, but it seems like the best way to do what I need would be to edit the pre-existing labels in the fsaverage aparc+aseg image. What I want is almost exclusively from the superior and rostral-middle frontal labels already there, I just need to limit their extent. Just wanted to know what you thought of this approach (although, to be honest, this might take some time, just to learn how to use tksurfer).
