Well, even though you didn't ask me, I figured I'd respond anyway
I'd love to see a command added (similar to the #spawnfix command) for adding waypoints. Where you would stand were you want the way point to be and enter the command #addwp xxxx (where xxxx is the gridID) and the command would automatically determine which wp# it would be (ie. there are already 3 wps for grid 10, so the next one is wp 4)
It would just be so much easier to run around and keep hitting a hotkey than it is to have to keep typing #wp add xxxxx y, #wp add xxxxx y+1....
But maybe that's just me
