How do I specify a feat to recharge on a short or long rest? Do long rests automatically recharge short rest features too?

EDIT: I'm thinking of something like Second Chance.

It’s an Action with “Limited Uses.”

Yes, long rests also recharge short test features, that’s why they say “short or long rest” and never just “short rest.”

Is there a way for this to be displayed as "Short or Long Rest" on the character sheet?

Short rest means “short or long rest,” it’s just a “shorthand” for it (pun intended).
