I think that you can.
When you visually locate the point that you want to add on the BaseCamp map, select the little "Red Flag" icon from the menu (top row).
And then stab that point right where you want it.
That's your new waypoint and it is added to the waypoint list.
Next, open the Route that you created in the waypoint list.
(Right click it, then select Open)
That will open the Properties window. Select the "Green Cross" icon to add your new waypoint.
Select the Arrow icon to move your new waypoint up or down the list.
Click Recalculate.
Yep I get all that too. In S&T you can be working on a route and use your cursor on a specific spot and click to create a waypoint which is immediately and automatically added to the route. Only if I somehow get a waypoint out of the correct sequence to I have to go in to move it.
I know I can go to the list on BaseCamp to work the list to get the stops in correct order. Part of the problem is I use specific spots on the map and I am not always sure which spot goes where when I go back to the list to organize. I need to come of with a system to place the waypoints on the list in the correct order or a way to control the order they appear on the list.
In S&T I click spot and get number 1 - the next spot I get number two. With BaseCamp I get names of what can be found at that location or some other title for that spot. I need to name them as I click starting each name with 1 - 2 - 3- or A - B -C or whatever. Then I still have to order my list before creating the route. I can go in later to make corrections. I will keep working in it when I get a chance. Still hoping to find someone who knows a program that promises to replace S&T.
