What methods are used to Automate Dot Correction?

What methods are used to Automate Dot Correction? I have a display board with approximately 60 LEDs.  I will be using my eyes to adjust each one. Are there any programs or control boards that will allow me to quickly switch  to address/adjust each LED?  I need it to go forward or backward, meaning next or previous LED and I would like a single potentiometer as the input adjustment., please help.

Thanks
