Unfortunately the Amiga can't wrap the display address halfway through a line; looking at how the hw is implemented that would have been a no-brainer if they had thought of it or deemed it interesting.

With AGA you can play games with re-setting the (low 16-bit) address pointers when you use 4x FMODE as you get more time between fetches to make it wrap midline. I'm toying with that for a Gauntlet thing I put time into at random intervals.
(I do have my logic off by one line for some reason I can't wrap my head around though, but the effect of seeing your bitmap starting from the beginning again when you get midway through the screen is so cool. IMO!)
