Belting....can you be trained to do it or are you just born with it or not born with it?

I really want/need to learn how to belt, because I want to be in
musical theatre when I grow up.

I can't belt (yet?).

Are some people just born with the skill to belt and some not?

I was not born with the belting "skill" does it mean I'm never going
to be able to learn how to belt and I'm just going to have to used
mixed voice for high notes for the rest of my life?

Can one be trained to belt?
