Direction of travel

This may be Garmin issue rather than a BC issue. If so, my apologies and please delete this question.

I have a Garmin Montana 610. When I draw a track in BC, the direction of travel is shown by a series of arrows along the track. When I transfer the track to the Garmin and open it to follow it in my kayak, there are no direction of travel arrows. Is it possible to include the arrows in the track on the Garmin? Is this something that I need to set in BC so that it copies the arrows as well as the track, or is this a function of the Montana?

thank you
