Refresh Counters Enhancement

Can you add to the refresh counters another action? Specifically, delete any on map counters that no longer have an definition and associated images.
I have replaced a number of counters with something that does it better. I know I can add in for the old counters the delete capability, but often I forget to do this. That is my fault. But, instead of users of my modules having to manually delete the obsolete counters, would it not be easier if the refresh counters did that job, automatically. Thus, any extant counters within a game that have lost their ‘definition and image files’ will be deleted during refresh counters. I would really like to eliminate those error messages of such & such counter cannot be found.
