Tape. Seems difficult, but if you have a steady hand, you could use some tape. An exacto knife, tape, and conductive pen should be all that you need, and it's removeable. I haven't tried it yet myself, but I've talked to a guy who did just that. Just get a 2cm long piece of tape (masking, scotch, etc.) and use the knife to cut a thin slice lengthwise along the tape, just wide enough to cover the grooves. Carefully set it in place, connect the dots, and your in business.
