Some questions about the 4000x series scopes

I am in the market to buy either a 4000x series or a 9000x series scope and I am currently comparing the specs of both models. One thing that I wasn't able to understand for the 4000x is the pre-trigger setting.

As I understand it, with the 9000x, the trigger reference point can be set anywhere. So I could set the reference point to the end and when a trigger occurs, I can go back and examine the entire acquisition memory to see what occurred prior to the trigger. Please correct me if I'm wrong.

But it isn't clear whether I can do the same thing with the 4000x. Based of things I have read in the manual, the data sheet etc, my feeling is that there are some restrictions. Can anybody please clarify this?
