Hi everyone!

I created a custom entity using the Advanced Customization Wizard and subsequently created a new tab that shows up in the main opportunities screen. To keep it simple the whole navigation is supposed to happen in roughly one place so that even our older folk can navigate the screens easily. Because of that I wanted to create a button that links to this tab inside my already existing button group for opportunities. However, when I select the action "Other" the new tab (which is a list of the new custom entities similar to e.g. "orders") does not show up with all the other system actions. I am aware that there are other actions available like linking to custom urls, pages or files but I am not sure how this would work as from my understanding the link to the tab from the new entity is different for every single opportunity. 

Is there any way to add the tab to the "System Act" list or do I have to tackle this problem differently?

Kind regards

Norman
