Hi @akosior,
currently each time sharing a project will create a copy, so yes. But more capabilities are currently in implementation, which is why I started this thread over here: Most important use cases for collaboration? - we’re very interested in the desired collaboration workflows that would make the simulation work easier for SimScalers. So if you have a specific workflow / use case in mind - please share! As always, more powerful collaboration capabilities will be deployed step by step - so there is always the possibility to re-prioritize based on feedback - so feel free to share your “ideal” SimScale collaboration functionality 
All the best,
David
