I don't think you can get a Dish receiver to tell you that, if it's not one of Dish's satellites. (A professional meter would do so, I imagine.) Just go by the peaking recommendations you saw above. If you get normal SS on 72 and 77, then I think the only adjustment needed for your dish is the skew.
Use the azimuth, elevation, and skew numbers for your location from the link below. Scroll down the satellite list to the "Multi-LNB" section and use the 1000.4/61.5, 72.7, 77 settings. If you're using a compass for the azimuth, use the magnetic listing and the dish mount side plates for aiming. Do not use the LNB arm...
and let it be a lesson to you, when you make any adjustments to your dish settings, mark where you started from. It will save you a ton of future headaches,
