Is it possible to create an arrow heading to waypoint (not arrow heading to destination)?

Please explain more what you mean--are you talking about the map display, and the car/cursor, the compass, the road, or something else?

In primo default you can display an arrow that shows the direction to destination (it is situated on the top od compass).
e.i. my current code ... <VSPRITE vec="destarrow.vpr" left=9.9% bottom=(%navigation.car.address.city != L"" && %navigation.car.is_incity ? 42% : 35%) w=9% z=49 align="CENTER" valign="CENTER" rotatemodel="navigation.destination_angle" scale=0.65 visible=(%navigation.has_route && %navigation.car_pos_valid)>

I would like to show an arrow that shows the direction to waypoint
