How to customize auto-generated infraction post content?
 

I have a forum, viewable only by moderators, into which I have the system place the threads that are generated by awarding of infractions (by moderators) and reported posts (by users). I find it very useful.

I'd like the post that is generated by infractions to show the ban reason (when applicable). The stock post shows everything but that:
Quote:
User:
Infraction:
Points: #
Administrative Note: (text)
Message to User: (text)

Why? --
a) because that Ban Reason is the only verbiage that the now-banned user will see, and
b) I'm not always happy with the stuff the moderators put in there, so I'd like to monitor it, and
c) it's a PITA to hunt that text down elsewhere, at least anywhere I've seen. (any tips of a better way?)

Is there a simple modification I can make to effect that customization?

I am using 3.8.4 PL2 (latest). I'm probably going to upgrade to 4.x in a few weeks, so I'm also curious as to whether this functionality is similar in the new world and whether this customization will apply over there as well.

Thanks.
