How to add to Category

Hi, I would like to be able to add my Events, to my actually events page, however this plug in does not let me select a Category to place the events in so I basically have to create 2 of the exact same posts.

Am I missing something? How can I do this? I need to be able to add various posts into my events page and would like to also be able to use this plugin to add upcoming event as well.
