I'm afraid you can only add symbols to the map one at a time. I would imagine 150 symbols would make the map hard to read though.

Hi. I'm trying to add arrows to my existing route and can only do the first one. After that it simply one add them in. Also - I'm trying to put about 150 in to show ohysical arrows boards on an event route; is there are quick way to do it rather than go through the edit process easch time? Thanks
