How to add Projects to a Category dynamically?

Hi All,

I'm looking for different ways to add Projects to a Category based on certain criteria. I'm aware of the dynamic options like 'User is the project owner', 'User is a team member of a project' etc. but this is not exactly what I want. Let me explain with an example.

Let's just say that I want to add all the Projects that belong to certain department. What are the different ways to achieve this?    

Thanks in Advance,
