Components, ports, interfaces & operations on SD

[Guillaume]

Hi,

I have a number of components that have several ports, which expose interfaces (themselves having operations defined)
When I put a component onto a sequence diagram, I've got show the embedded elements (ports & interfaces) so I can get the list of available operations.
Problem is that the diagram gets too crowded for the taste of my client, so I'd like to know if there's any way to get all operations that are exposed throughout all interfaces provided by the component on the component itself (without having to define the operation directly onto the component).
In other words, can I make a component inherit from the embedded elements' operations on a SD?

thanks,
Guillaume
