VS Code how to make a copy of the snippets so I can edit without messing up the original

Question

Very new to VSC. Not really sure how the whole commit-merge-push-pull thing works. Seems like syncing will "pull" the blank files from the server and replace the files on my computer that I've been working on. Scary.

I have made a copy of the snippets file that is given to me by the company and edited it. I've done F1: preferences: configure user snippets. But when I begin to type a snippet it shows two of every single snippet, so obviously it's looking at both snippet files.

How do I tell VSC to use my snippet file and not both?

And what's the best way to get the updated snippets for the week and merge the few additions or changes into my snippet file? (they don't tell us what they've changed)
