Add event form limit the selection of categories

Hi all,

Considering purchasing Pro version of this plugin however, not sure that what I need to do is possible? Hoping someone can help.

In the add event form the user/visitor need to select for witch category the event is. This user/visitor can select all categorys.

Is there a way to limit the selection of categories? I want to be able to add a certain category to an event as admin only and not via the add event form.

Is there a way to to this in the free version or can i modify this in the pro version?

Let me know
