[amsat-bb] Simulate past passes in MacDoppler w/o changing OS date/time?

[John Brier]

I just setup MacDoppler last night and got it to do basically what I
wanted but I can't figure out if it's possible to simulate past/future
passes beyond the 6 hour +/- changes you can make with the slider. I
can get beyond that limit if I change the system date/time but I'd
prefer not to have to do that to get what I want.

I did see you can get predictions for anytime but what I'm interested
in is not just that, but watching the map from the past passes.

Is there a way to do that?
