Duplicate custom fields to other posts?

Hi, I’m wondering if there is a way to copy/duplicate custom fields from one post to another.

I am creating multiple posts with the same 4 custom fields, and find myself adding/typing/saving over and over for each field in each new post. It’s very repetitive, and it seems there must be a way to streamline this.

I am not really a WordPress programmer, so I’m hoping there is a minimally technical solution? It seems like it would be a common occurence.
Thanks…
