Time saving trick for dancing line effect?

I’m working on a project in a hand drawn style, and I want to have jittering/dancing lines, as seen in this animation by animalcolm (I love this, btw):

I’m wondering if there is an effect or script in Harmony that can automatically create that dancing line effect, or if it has to be done by manually cycling through multiple drawings. A couple years ago, before I moved over to Toon Boom, I was using Anime Studio, which had a dancing line effect. I can certainly do it manually, but an effect would obviously save a lot of time. Any advice or secret knowledge would be appreciated!
