Does Rosetta support uploading translations of products to upstream?

[atie]

I have recently translated some products registered in Rosetta, I mean "not 
the packages in Ubuntu versions". And, the translations are new for Korean 
even the product projects have no ko_KR translations.

In this case, does Rosetta support uploading them to the product projects 
automatically or with predefined rules between Rosetta and projects?

Or do I need to individually download translations and send them to the 
projects?

I hope former, if not will later be in plan soon?
