I did post a cheat sheet with concentration vs vAg at 20 and 40 deg C. It was appended to one of those threads.
And, the equations I use are similar to those in the references I gave above. It is a page or more of calculations. They involve PKSP values for each halide involved, Junction Potential calculations, natural log functions and conversion of temperature to Kelvin and then offsetting the value of all based on degrees K. And, before you get to vAg you have to know the negative log of the silver ion concentration (or pAg) in a manner similar to pH calculations.
My "system" is having had to do it daily for about 15 years.
