How to include a copyright in a Capella model?

I am trying to include a “copyright mention” in a Capella model. I would like the copyright to be visible in the diagrams/viewpoints and, if possible, in the model explorer. Do you have any suggestion?
Best regards

Maybe I’m a little late on this topic.
We have developped a tiny viewpoint that allows to display a Notice pop-up window whenever the model is opened.
The Notice element is stored in the model explorer.
It can be easily improved for integrating a layer that could be activated on each diagram.
Please let me know if you are interested.

Go Capella with Artal on

Hello benoit,
Thank you for your answer. (Sorry for my late reply)
I would be very interested in testing your tiny viewpoint.
Best regards,
