Actually just now on my way home discovered a new feature ….

If I click the button for a single wipe, it also pops up the wiper dialog on the touch screen, so all the configurations are right there. You have to act fast before it disappears , so it’s possible that it’s always been there but I didn’t look at the screen right after pressing the button. Anyway, that greatly simplifies the process. While the controls are still touch screen at least I don’t have to click through the menu to find the controls
