Whomever told you this is wrong. There is such a feature but, 1) it's controlled by maintenance and 2) it can only be done with no guests being onboard. Never have I seen and/or heard of this happening with guests from the folks I've known there for 3 years.
As another poster has said, Bays 1 and 2 are Green, Bays 3 and 4 are Orange. They've almost always run every single day, baring any issues. Basically, Maintenance has to reconfigure the ride profile and upload the old one/change the videos. That's all there is to it. It takes about 2-3 hours.
Oh, I wish it were that simple. Per their training, Green always had to have a lower wait time than the Orange side so as to not force people to go on the Orange if Green had a higher wait time. Even if the Green side was higher in wait time than the Orange, Orange always had to be higher, which segueways into the next bit...
This change is actually not a good thing. This was deemed from other higher powers who only looked at the numbers instead of the rules that govern the attraction. Let's just say expect Space to go down a LOT more often now (and I'm not referencing the Green bay going Orange).
