More user id for one key

hi,
in a key one can define more user id. in gpa there is no way to define 
more user id neithe when you generate a key neither later. eg. in WinPT 
(the windows frontend for gnupg) there is a submenu when you right-click 
on a row for user ids and sub keys. this would be useful for gpa too!
this is the command line tools --edit-key's subcommand like :
adduid
deluid
etc.
is there any chance to use it in the near future?
yours.
