XF 1.5 One forum that displays all posts

My forum is organized by boat brands and there are dozens of them. One of the popular features on my current VB board is a single forum that is configured to show all posts from all forums. Is this mod possible in XF?

XenForo does have something similar, Recent Activity

Except that in IPB 4.1's case, it's not an optional thing that users may or may not look at, it's now taken the place of "View New Content," if you're smart enough to figure out how to get there (Activity > My Activity Streams > Unread Content). I literally had no idea what I was looking at when I visited the support forums the other day... and I've been running their software for nearly eight years. :(

My apologies to the OP for slightly derailing the thread. ;)
