FR Dash and Arrow adjustments

Can we please have two functions to fine tune the Arrowheads and Dashes for Stokes?

  1. A button to “swap” arrow head orientation.

  2. A button to alternate the dashes/gaps in the dash settings.

Two lines explaining the difference:

   _ _ _ _ _ 
  _ _ _ _ _ _

Low priority…but handy in my world.
(indesign has it and the function is used often)
