Tracking bad tank spots

It would be great if preform gave us the ability to track bad tank spots. As bad spots grow over time, the tank is still useful, but one has to manually track (I use sharpie on the tank itself) where to avoid. Can we create “bad zones” and track those against given tank IDs?

We’ve seen this suggestion a few times and it’s something we’re actively considering. I’m curious as to what you mean by your using sharpie on the tank itself.

I am curious about this as well. Hopefully you are not drawing directly on the tank.
