Reverse Audio Data in Guitar Tracks Pro 4

In Guitar Tracks Pro 4: I'm familiar with reversing audio clips in other versions of Guitar Tracks, but I've just started using GT Pro 4, so I'm kind of unfamiliar with how it differs. I can't find the 'reverse' feature. The Help section, as well as every search I've done on this forum and google echos how it's done in the other versions: Process > Audio > Reverse. When I go to Process, I don't have an "Audio" tab in my drop down menu. I have "Audio FX", but I can't find "Reverse" in there. Is this not available in Pro 4, am I just blind, or is it named something else?.. cuz it took me an hour to figure out that "Bounce To Clip" was "Combine" in the older version.
