Additional Thread Icons (Not Status Related)
 

I'm looking for a way to add additional thread icons, on the right side of the Thread Title. This should not impact the status icons. I'm just looking for another way to identify thread "types" using icons.

For example: Several threads in my forums are stock and options trades, when the tread creator posts a new thread I would like for them to be able to select an icon that will represent that the trade is active. Then when they are finished, they should be able to change the trade to inactive. Discussion should still continue after the trade is inactive which is why I don't want to use the status icons. And I don't care for the idea of creating extra threads to discuss the trades.

Thanks in advance,
Nate

Maybe using the prefixes system?
