[O] Simultaneously showing multiple todo keyword sequences

[Zans M]

Lets say I have two sequences of TODO keywords:

"TODO" "|" "DONE"

"WORKING" "|" "BROKEN" 

At the moment I can show only one of the states at a time, but what if my task can be in two states at once (one from each sequence), ie

* [TODO] [BROKEN] Build interface for webapp

Would anyone know how to do this, and how to setup key commands so that I could cycle through each sequence independently?
