Default can a scanner be used to monitor fuel mixture imbalances b4 it kills the cat?

Is there a way to routinely "DIY" monitor you cars systems to alert you as to a potential problem coming up before lights and codes appear?
Ive noticed (reading only) that IMs on a scanner informs you to combustion/fuel data in terms of range in %. When those % swing out of the allowable % ranges,contaminates (oxides and even blowby & more?)become significant enough to begin fouling the cats and possibly other components.
Can scanners or even code readers give us data we can use to accomplish this preventative smog maintenance?


PS
