How to merge 2 operations of a class?

I have 2 operations in one UML class and there is a lot of diagrams use them. Now I want to merge this 2 into 1 operation and I don’t want to manually update other diagrams already use them.

Normally Visual Paradigm allows to merge different element into one…but it does not apply for operation.

Please advice and thanks

Hi survivor73,

Can you explain how your diagrams ‘use’ the operation? I mean is it some kind of reference, or like the message in Sequence Diagram that point to this operation, or other usages? Thank you.

Antony.
