I always known for years using /find or /findfriend always adds a waypoint for you even if your datapad is full. For playing years we do have to clean up old places, especially as game changes and shops-old hunting ground no longer valid for us. I always get "you have too many waypoints" message.
Well for a bit time I would use a alt account to save waypoints to add to them with /findfriend then change edit the name in my datapad. After just thinking recently "why not just add myself in friends list?" My long time close girlfriend who used to play swg used to save herself on her friends list for notification that she was still online. I was like "lol?"
Ok so add your own toons name into friendlist(the one your logged into). If your out of room in your datapad you do not have to clean up waypoints(delete). you want to keep them right?!?! Then do /findfriend <yourtoonsname> <----spelling it however you toons name is. Then Be sure to change or edit the name of that waypoint in your datapad to something else. If you didn't then next time you do a /findfriend it will update it where you move to.
It has always worked to /find star for starport even if ur datapad is full and also with ur friends or alt(/findfriend). It works for yourself as well.
I hope this helps and I know how frustrating it is to have to delete memorable old /waypoints
The only draw back on this is doing vendor waypoint on bazaar search, and in saving email waypoints

this will not work. Although during your travels you can save many more of them instead of /way
