Where/How to Edit/Change/remove Access Point(s)

The Feature Reference Guide and the Admin Guide make one believe they can Edit this information as well as Delete them.
Yet there seems to be NO Details about this.

When I do Try and Delete one where it appears I have multiples, I get the following error:

So I am just curious..... How can these be edited or changed WITHOUT doing a rediscovery or delete/add agent???

Especially since one I need to change is one of my remote proxy servers.

   thanks;
