I use ffp scopes and use holdover for shooting distances past my zero. I have input all necessary info into the application. Is there any way to manually modify the reticles pictures it produces? I have found on a couple of my rifles that the holdover point is roughly 1/2+ mildot high at ranges over 75 yards. I'm shooting ground squirrels from 30 yards to 100 yards. thanks

And NO, I don't want to switch to strelok or any other ap. I use my computer and don't want to use my phone.
