Integrating custom states

I've created a few custom states aside from 'Needs Review' in my particular workflow. I cloned the 'needs_review_page' display in the 'workbench moderation' view to create new pages reflecting the new states by changing the 'Workbench Moderation: State' filter value. Now I'm unsure of how to proceed. Is there a place in the UI where I can replace the 'Needs Review' tab that appears in 'My Workbench' to reflect these new states? Ideally, for the four custom states I've made, I'd like content in a given state to appear under it's own tab for all authors/editors that have moderation rights for that state.

Thanks!
