There probably is, but I never had the guts to try it out.
I know that you need to tape both films together at the start, emulsion out, and feed them that side first.
It's easier for 120 as you can make them simply follow each other using a bit of tape, they take the same amount of space as a roll of 220.
But for 35mm I think you need to use stainless reels accompanied by incense burning and a few chants...
