Is there a way I can make my focus specificly appear on one state?

I have made a focus that talks about industrializing inland, is there a way for me to make it so i can select which state the factories spawn in on?

On the line which has:

random_owned_controlled_state ={

Replace it with

STATEID = {

Where STATEID is the ID of the state you want to add the factory to

Ty a lot
