I recently watched a video where they changed/flipped the tangent direction of a spline to a line by right clicking the Tangent relation in the dialog box of Existing relations dialog and choosing "Flip Relation" I wish this where available for arcs as well. Does any one know an easy way to flip the relation when working with arcs in a sketch?

When the sketch is simple the obvious answer is just delete it and sketch a new one, but sometimes you'll be sketching and start constraining your sketch and the direction will flip on its own, depending on the sketch this can sometimes bugger it all up. It would be nice if this functionality were extended to arcs as well.
