You certainly could create your own version of the app to do what you want. It would just be a matter of locating the part of the current script that you need and pasting that into your new app and then modifying to do what you want.
I have created some of my own Admin apps but not this one.
I would advise not updating the current Operations Monitor app. Make a duplicate and then modify.
I am not of a way to modify the QMC itself. I doubt that you would want to do that as updates could get tricky.
