Yes. You need to find the asset name for the bot planes that spawn. Once you find that you need to select the unit box and select whicever plane you wanted. Weapon wise you will want to choose which weapon loadout to use as well. SAve it after changes and launch. You also need to load the environment and actual mission to do this correctly. Let me know if you need help with it.
