When I go to NM, which is 4,000' compared to 100' elev. in LA, I look at the ballistic programs and make note of the change. It's usually a click or two difference at 400-500 yds. Not enough to worry about at lesser distances. It's not hard to remember the difference and dial accordingly. I could have turrets made for each elevation, but have never seen the necessity to do so.
