If I may make a suggestion...
If you start adding formations to the root AICarriers.cfg file, you can rapidly wind up with an immensely bloated, unwieldy, and fairly unusable AICarriers menu once you load it into the sim.
The trick is to leave the root .cfg file alone. Don't add formations to it. Instead, make new .cfg files in the conf.d folder. That's what it's there for. This makes it possible to, instead of adding more and more pages to the in-sim menus, only add the formations and ships you plan on using for the particular session.
Once you've made the different .cfg files for the different formations and/or individual ships you desire, store them in another folder someplace, and only swap in the formations you desire. I personally made a folder called BAXX under the conf.d folder. In it, I literally have dozens, maybe a hundred or so, .cfg files I can use. I have ships, individually, and in different formations, helicopter sling loads, the list is vast. BUT, doing it this way permits me to keep a very manageable in-sim AIC menu tree, and I know just where to find the formation I desire for the simming I plan to do this session. I simply copy the desired.cfg file into the conf.d folder from the BAXX folder, deleting whatever may be in there. When I decide on a different scenario, I do it again, with a different .cfg file.
I never have more than two, at most ever three, menu pages in-sim. Much easier to find what I want quickly and easily, rather than going through page after page of menu choices. I want to do CQ's on the Numb-Nutz, I load that .cfg file into the conf.d folder. Next time, I decide I want to practice hoisting helicopter, or MV-22, sling loads, I delete the Numb-Nutz .cfg file, and load in the sling loads .cfg file. Easy to find the load I want to carry, and away I go.
All this is only a suggestion for a way to use AICarriers. Naturally, it's your sim, and you can use it as you choose.
As always, the point is to have fun with it
