Yes you can modify the top file by hand to use itp files generated in two
different ways.

If you have an rtp file for you carbohydrate you should be able to run
pdb2gmx and then you should also be able to generate vsite. Or you can
generate them using your own scripts. Of course you only need them if you
have the respective groups (e.g. CH3).
