Paragrams Theme – Help with creating custom dropdown menu

Hi there!
I’m running the very nice theme Paragrams from WPshower and it works fine. My posts categories is showing nicely in the first dropdown menu. Now to my question: Is it possible to create a second dropdown menu “item”, in the same menu, that is based on different data then categories. I would like to have a page where I present all the staff of my company and I would like to be able to sort them out (through a drop down) by their working title (which I’ve added through a separete plugin).

Here’s an image describing what I want to do

Can you please help me?

Kind regards,
Karl
