Lars, there isn't unfortunately. Might I ask why you are implementing a project first and then sub-project sourcing project? David Morel
How about building a custom field that copies the title when a project is created? That way, when you make a sub-project or a follow-on it is only a matter of copy-pasting on the creation page. Be aware, however, that Ariba does not allow identical workspace names to be created one right after another, meaning that if you would want to have identically named workspaces, then these would have to be created with other workspaces being created in between.
