I have spent the last hour trying to gain control of the list. What I would like to do is to remove the icons from the map and deal with them piecemeal or one at a time. Adding and removing them as I see fit. Certainly that must be possible, correct :question.

My strategy is something along the lines of this:

I keep what I call my Master list ... a list of everything I can find about an area or park.  Then, when I am mapping out an area that represents my trip plans, I make another file by copying and pasting the "important" things to a new file.  

There are two ways to select items to be copied:  (a) select items in the left window or (b) select items directly from the map.  This process is much quicker if you select groups of items (which can be done on a Windows based system by holding down the SHIFT key while select items ... its a "group" select.  I'm not sure how you'd do this on an Apple ... been decades since I've played with one).

Then you use the Edit menu to copy the selected items.  From here, you open a new file and paste (again using the Edit feature) the selected items to it.  Saving this file at this stage has two advantages.  You can come back to it later or you can continue the copy/paste series by returning to the "master," selecting more items and then re-opening (and pasting) additional selections.  

BTW:  I've created custom icons, smaller than those typically assigned to the waypoints by Mapsource, to reduce screen clutter on my GPS.  But, that's another lesson.
