Great job man, tried it out and it works great! I could definitely see something like this being a must-have for all future signature campaign operators once it's 100% finished and polished.
It doesn't work like this in the post list page, so if someone could help me on this that would be great.
I'm not completely sure what you are asking/needing here, but maybe try asking in the "Meta" subforum? Maybe that is something theymos could help you with. Apologies if I misunderstood your question.
