I can't say I've ever seen it. I had a look just a couple of weeks ago at the options on new posts after someone else asked me about it, but there was nothing available to do like you ask. Might want to search over at vbulletin.org, perhaps someone has made a mod of it..
I personally just use the frontpage (vbAdvanced) at http://www.free-dc.org I need to actually update to the latest to hopefully fix the birthday panel at some point..
