Include forum name in post report

[Skyline_GT]

I wonder where is the place to edit the title of the thread for post reports. I want to add that specific forum name in the title of the thread so it is easier for mods to know whether that thread is from their section.

Thanks.

I found the place, but when I replace it with $reportinfo[forumtitle] - Reported Post by $reportinfo[rusername]

It only shows Reported Post - Reported Post by username

instead of the forum title.
