Indeed, I also have not seen this. Also, it`s nice that you can see what IPs are currently blocked by IDS, for example, but it would be nicer if you could see right there a list like "previously blocked IPs".
I think that by default all IPs that wrong you in any way should be kept on an easily accessible list. Many times an attack will come again from one of these IPs and you need to know and correlate this.
