Modules - Profiles - Fields...

I was wanting to add a custom (dynamic) drop down list to the profie asking my users where they work (department). We add/change/delete departments in a certain database regularly... So I wanted things to be dynamic from that database...

I know how to connect to a database ant all of the like - however I want to be able to use the Modules - Profiles - Fields... location to add it (getting all of the nice things that come with using that little page - required, positioning on page, etc).

Is this possible? I know I can create a static drop down by adding departments in the standard drop down that the fields page will provide you - I am looking for a dynamic one...

Thanks for any help!!
