I've seen this suggested many times on this forum, but never added my voice. Adjusting ticket prices is by far the least fun aspect of the game, and late-game a lot of time can be spent changing them. All I really want to be able to do is to set a 'target' price satisfaction (e.g. all tickets priced at green satisfaction) and let the game do the pricing, so I can concentrate on actually playing it rather than micromanaging prices.
