Convert MMC console from usermode to author mode

I have an MMC console that is saved in usermode. It has worked well for some time, but when it was created to displaying only 10,000 objects. Now it tries to display 13,000. So everytime I open it, I get an error message warning me that not all of the objects were displayed.

Is there a way to convert this back to author mode so that I can increase the number of objects to display?

Thanks
