radio options sub category

[Mt5_Roie]

So I'm working on a NTTR training mission and I have several different aircraft available as aggressors. Right now if a person hits F10 for radio options they see all the options. I want them to see a options called "A-A Aggressors" that would take them to a sub category listing all the different aircraft types they can go up against. I thought I saw this on other missions but not sure how its done.
