When creating a circle geometry for a roundabout, it only seems possible to create geometry in an anti-clockwise direction.  I've tried creating an arc with a sweep angle of 360 degrees in a clockwise direction, but this closes the geometry to create an anti clockwise circle.  In the UK all roundabouts run clockwise, so it makes sense to run our geometry clockwise, or all our stations and profiles will run backwards.  Will get even worse if trying to do a Stockdale design, as all our entries and exits will run backwards.

Is there a workaround, or can this be raised as an enhancement request?
