Linking packages to repos in other orgs

When publishing a nuget package to my user account where the associated repo is in an organization owned by my account, I am only able to link the package to a repo owned directly by my account and not to a repo in an organization owned by my account.
Is there a way to link packages to repos in my organizations not just in my account ?
If not then I guess we can forget about linking packages to repos as that would require one big flat repo space instead of our current ‘hierarchy’ using orgs.
The idea is that we want to have one single nuget source that is fed by multiple repos in different organizations ( and possibly owned by different users )

I think you mean a global nuget package. It’s a new feature and there is already an issue.

Thanks - I looked around but can’t find anything regarding global packages on github or here on discourse or through google search.
Do you have a link to any documentation/discussion on global packages ?
