ATN X Site PRO Mil Reticle and elevation adjustment.

Im looking at the ATN X site again now that I heard they updated the firmware with a mil-dot reticle. 

Does anyone know the answer to the questions below?

1) Can the elevation adjustment be easily made to compensate for different target ranges (similar to clicking a normal scope)? I dont want to have to re-zero for each range. 

2) Does the new mil-dot reticle scale with zoom like a FFP or is it "true" at only one magnification level?

Thanks in advance, 

Brian
