Using the calendar view to show categories instead

Hi Tuan,
Awesome Extension, will give it a high review as it was a good purchase.
I was wondering if you can teach me if the following is possible.

I have a menu pointing at a monthly calendar, however there are numerous events each day >70, so I was wondering if it is possible to use the calendar view to show categories in there, so that the calendar doesn't get overfilled with too many events.

Thanks
B
