set up random groups and storing #help


I have set up random groups for random characters, numbers, chars and numbers, and would like to set this unit for prosigns, if possible. I've also done call signs.  When I select CW abbrevs, I thought I was selecting prosigns, but it doesn't seem so as I only get groups of random chars. not SK or any other prosigns.  Is it even possible to set up random  prosigns?
