Hello,

If it's only for the visual effect, swap the ArrowHead and ArrowBase shapes. That will make the arrow look as if pointing in the opposite direction, without actually changing its OriginBox and DestBox nodes.

If you need the arrow to go from its original destination to its original source, I cant think of another way to do that except this one:

- create a new arrow from the old destination to the old source
- copy the Segment property
- copy all CtrlPtX and CtrlPtY values
- delete the old arrow
