seat dragging turns

I can drag seat in front pretty confidently now.
But the problem is i do all my freestyle in a undercovered area at the local primary school which is about 20m end to end and when i’m seat dragging easliy and then have to get off coz im about to hit a wall. I’ve tried turning around but i can’t seem to do it. the uni just leans over a lot and i usually get bucked off.

Does anyone have any tips for turning around when seat dragging?
