No to both.  Modification of .GRP files *is* built in to Program Manager.
(actually, almost everything Windows does is "built-in" in this sense)
Other programs can modify .GRP files by requesting that a change be made by
Program Manager.  This is how you can drag a program from the File Manager
into a Program Manager group, and have it work properly.  The actual
mechanism is a rather tedious process involving DDE, but it can be done
rather easily.  Most Windows application installation programs do this.
