There is! It says in a little pop up if you hold shift it will fully upgrade as much as you can afford
....i can't find the pop up, where is it?
thank you either way :] gonna have to replay the game now that i know about this
Its in the bottom of the ascension panel
Even with this, I'm prestiging one car over and over and I have to click 38 times while holding the shift key every time. It might break the game, but an "auto upgrade to prestige" function would be great.
