I expect the answer to my question below is no, as I can't find one by searching manuals or forum. And in the wild this certainly doesn't make sense.
I keep some games on 5 ball for my wife and other family members. Is there an easy way to toggle between 3 and 5 ball games on modern pins? Besides, for example, on a late model Stern:
open coin door
toggle to & select Adj menu
select SPI adj
toggle to menu item ~21 for balls per game
select, toggle to change, select/install
back - back - back button
close coin door
I don't really care about documenting and keeping high scores on the games - I'll snap a photo if I get a great score. When we have a party I usually reset the high scores, and sometimes reset scores and install easy settings.
I'd love to be able to walk up and hit a button to switch # balls, or even have a short cut at the top menu after opening the coin door. I could do the steps above to switch from 5 to 3 balls, but I would also have to reset the games to 5 ball afterwards. My wife likes to play (a good thing), but would never go through the motions above to alter the balls per game.
