Waypoint location to show on map

[Sheylara]

I was wondering if it's possible to have it so that when you type, for example, /waypoint 100,100,100, a dot will appear on the ingame map to show exactly where that location is?

Sometimes, following the wispy trail is frustrating because of impassble hills and such. So, knowing exactly where a particular loc is would be a great help.

(If there already IS such a UI, can someone point me to it, please?)

Thank you to all UI authors for the great work you've done! Your UIs have enriched my gaming experience.
