For anyone looking for the kingdom on the southeast and what's the Sub points for, yes its for future update!
I should've made it clear instead of making it vague/somekind of secret contents. So yeah my bad... XD
Have you tried the "Remember Boneka Command" in the option menu? It will make the game put your ally to your last Boneka command (except support and guard).
If you're talking about reapplying Full Control every battle, I can only say I have something in mind but it require to advance the story, so yeah it's not available as of now.
Thank you for your feedback!
