Trying to add rabbits to town

So I know that you can spawn rabbits into the town and promote them to a worker and all the jobs and have them run around and do stuff but they are not counted as a citizen. Is there a console command for adding a spawned entity to the citizen list?

I know you’re not supposed to play with the bunnies yet but… I couldn’t resist.

i need this one to, can some one help about this?
