SubSrf tiling - Odd offsets and half brick finish - Overlapping

I have created a sub-surfaces to tile objects using relative-items and am unsure of whether I can get the half tiles at each ends of the wall?

How can I get the pattern to work when the V surface division is Odd?

Is PT Grid offset the only way I could overlap these as well?
