Content Fragment creation and Content Fragment authoring is a two - step process.
If you want to make this as a one step process. You will have to write custom logic, as this kind of usecase is rare and not configurable.
As shown in above snippet, you can directly go into the Content Fragment by clicking the Open button and author the Content.
You can control this by Front End Logic. Capturing the DOM elements and leading the user to Fragment Authoring page.
You might have to hide Done button, in Success alert shown in above screen shot. And disable any option which could allow user to close this Success Alert Message
