Is it possible to copy a part of the seq. diagram?

[Gabor]

Hi,

I have a sequence diagram, and some part of them I have to use in another sequence diagram.

So it would be very convenient, to mark out the needed part, create a new sequence diagram for that part, and reference them from the others.

Is it possible with EA?

If I try to copy the elements, I can't assign the messages.

Thanks in advance

Gabor
