Splitting diagram - duplicate elements

[Doctor]

Hi all,

I'm facing following situation. In my scenario diagram I'm describing system response on multiple inputs. Now I would like to split the diagram into more diagrams - I know it is possible using the copy feature, but ...

... but I have got duplicate elements (lifelines) with same name when copying the diagram into same package. The elements are mostly the same in both diagrams. My idea is not to loose the already existing scenario parts, but put them into sperate diagrams only.

I know it is not proper procedure, because there shall be more different UseCases. But in this stage I'm describing the already existing system and have no use case diagrams.
 
Thank you in advance

Oooh, I can just envisage a 'diagram refactor' mode, in which you can have several diagrams open in tiled windows, and you can then drag elements between diagrams.

Well, it will be Christmas soon ! (Or "the holiday season" as those godfearing Americans put it ! - well, yes, there's Christmas day, Boxing day, and then Hogmanay, so I suppose it is a bit of a season of holidays after all.)
