Rotate Grid Lines (Sections too)

The direction grid lines and sections are placed affects which end the grid head and section head are placed. It’s easy enought to manually switch the heads (maybe even through Dynamo) but then you have to do it for every view (boo). But, if you rotate the grid/section 180 degress, it solves the issue! So far I don’t see a way to rotate grid lines (haven’t tried it with sections yet). Thoughts?
