Tagging or Grouping

I am looking for a way to ID tasks beyond color or assignment. Is there a way to have a development team tag so I can sort by all development team tasks beyond indenting or coloring them? Thinking about a task that is cross-functional, so I want to be able to see it in multiple places.

I.e.,

Home Page

  • Art Team
    • Tom
      • Assigned Project 1
  • Development Team
    • Sally
      • Assigned Project 1

So I could find this under Sally, Tom, the Development or Art team.
