Cloud21- Documents tab in Project: doc created from here does not attach to the object

In the Project window (i.e. Project Scope and Supply) the Documents tab allows a user to create a document directly from the Project/Subproject/Activity. We promote this as best practice--creating the document directly from the applicable object--as you don’t have to add an additional step to connect the document. This is especially true in the Projects world, as documentation is often extensive in project-based industries. In Apps 10, this works as expected: in the Documents tab I use the function to create a new document and, when I finish, it is connected to the object I created it from: the project, subproject, or activity. However, in Cloud21, I follow this same process but, when complete, the new document is not connected. I have to exit the project, look for the document, and then manually connect it. Is this a bug or a gap in the design?
