I'm thinking that probably we should add this feature to the CLI we're using to keep the things simple here.

What do you think?

You mean create pull request to copy-github-labels-cli repository ?

Yeah, it sounds reasonable to me

I'll try to finish it in copy-github-labels repository this week :)

I've created issue in cli repository, because I'm not sure if this project is still maintained.
