I'm not sure what a .doc document would do for us? Maybe I'm missing
something.
Anyway, the best thing to do is to read
http://www.sagemath.org/doc/developer/walk_through.html and then attach a
patch to a ticket for this. This can be done by going to
http://trac.sagemath.org/sage_trac/ and following the instructions for
getting an account, then stating the problem on a new ticket as you see it.
(I don't feel like I understand exactly what you want enough to state it
properly.)
Then you could even cut and paste the code right on the ticket, or create a
patch if you are able to follow the patch-creation instructions. Plus,
then you would automatically get emails on updates!
