[Plugin: CGM Event Calendar] Upcoming events

Hi, I have looked through the change log relating to the CGM Event Calender, and it says this:

0.7.8

(09/17/2010) * Upcoming events now go out 6 months looking for events.

Is there any way of extending this. My company will need to show events that are over a year in the future.

If anyone could help it would be much appreciated.
