There's ways to test it.
Say you wanted to do something once the print count hit 5. You could make it go in a loop where it would decrement 4 and increment 5 after a short delay. Thus, it would cause a printCountOverflow once the print count was 5, since 5 + 5 = 10.
Edit: You would need to break out of the loop somehow once the printCountOverflow was reached. Usually cancelevents does the job.
It can be a daunting and complex task to apply this type of logic to event builds, but it is possible. I don't think this addon is completely necessary.
