Feature Request: Copy / convert complete design diagram to diagram

[GoogleCodeExporter]

What steps will reproduce the problem?
1.
2.
3.

What is the expected output?
There should be an option to copy all the items from a design diagram into a 
new diagram. This could be realized by adding a context menu item for each 
design diagram element in the Model View named "Copy to new diagram".
This would speed up the process of translation a rough sketch in a Design 
Diagram to a Pro View in the extended diagram.
Maybe one could even think of an option "convert to diagram" which would create 
a new diagram, copy all items and delete the old domain diagram.

What do you see instead?
Feature not implemented


What version of the product are you using?
20101021 beta x64

On what operating system?
