You can try a few air rootings. On one of the runners, preferably at a joint, take a knife and scrape lightly the a short section of the vine. Put some rootone on it, put a wad of wet spaghnum moss on it and wrap the area with a piece of aluminum foil. Give it 5 or so weeks and check it for roots. If you have some then cut the section out in early spring and transplant it.
