Gitlab.com artifact/release only repo

Is it possible to create a release only repo on gitlab.com?

Files are built internally on teamcity.

I just want to attach a tag and release a binary, So they can reached externally.

I already mirror lots of internal projects on gitlab.com and it works great for external access.

It would be nice if we could use the same infrastructure…

I can create a repo with a pipeline that get the release from teamcity and builds a release in our internal gitlab, but how can I mirror the releases?

Os should I just go for an azure blobstore?
