Adding wireless networks for all users on a computer

My buisness uses three different computers with logins for about 30 users (Win XP latest SP). We use the wireless networks at severla different locations and I would like to know if it is possible add the wireless networks (Names, passwords) for all users without having the individual user connect to each individual network once. Tried to do this from GPEDIT and computer managment but can't find anything useful. The computers use the intel proset which is disabled because of problems, so we are using the XP wireless interface.
