Retrofit the windscreen wiper interval?! MK7

Hey, don’t have a real disc wiper interval on my Mk7 tournament ANL 1.8TD (Classic equipment (I believe, kp)). Only the two quick steps, when you push the lever upwards. and then the one “interval level” when you push it down. With the absence of the interval adjustment wheel, on the disc wiper lever. Now my Essi wipes only all 7sec in the interval. the time span is usually too large. but when I turn on the fast step, then it’s a lot too fast. : you can simply replace the Sonen windscreen wiper lever with interval wheel with the other one and then it works? or you still have to put cables, relays are replaced, etc.
