Hi,
Thanks for the interest in our plugins. I can answer your questions.
Have you tried using the category system for this?
By default the plugin creates the event views(month,list, map, photo, etc) for each event category.
So if you have a category called lettuce you can see all the views here:
yoursite.com/events/category/lettuce/
That could be a way to do this.
The Filter Bar does create links you could link to for each sub organization if they are a category too, but the link is not as pretty.
Let me know if you have any follow up questions.
Thanks
