So I have done it before, and now I can't figure out for the life of me how to do it. I have created a custom element through stereotypes and customization. I am able to right click in the containment tree and add the element to the model and manipulate it that way. However, I would like to add it to the quick element creator pannel in any diagram. I'd especially like to add it to the common section, under the comment type. Does anyone have the documentation for how to do this? I know it was covered in the 2024 MBSE Cyber Symposium, but of course I managed to delete the model I built there. Thanks!
