[Plugin: All-in-One Event Calendar] Multiple taxonomies?

Is it possible to integrate an additional taxonomy term?

For instance, in my site, I am listing dance events.

I have a taxonomy which is threefold:
Event Type (class, workshop, performance)
Event Topic (jazz, ballet, hip hop)
Event Location (by region: N. State, S. State, Big City 1, Big City 2).

I currently have it set up so “Type” and “Topic” share the “Categories” dropdown. And then I am using tags for location/region. I have altered the code to have the category and tags return AND results, rather than OR results. So they can cross reference type and location or topic and location, but not all three taxonomies at present.

Ideally, they would be able to have three separate dropdowns, and could choose a type, topic, and location/region, and get the filtered results. So they can view a calendar with ONLY “jazz classes in Big City1” or “hip hop workshops in N. State”.

I know you guys are doing a lot with the calendar and releasing every couple of weeks. SO grateful for your hard work. And I know you have already nodded at the idea of having a front-end toggle in the future where the user will be able to choose if they want AND results or OR results, which I think will be great. But as for the multiple taxonomies in their own dropdown, I wonder how difficult this would be to do; and if it is not in the pipeline for a release in the near future, if there is anyone savvy to integrating taxonomy with ai1ec that could help me do this for myself?
