Is there a way an input to be integrated right below the Toolbar of the editor?

Greetings, community!

I have the following use case I want to point your attention to - I want to display the **MDX editor'**s Toolbar onto the top of my Card component(as you can see in the screenshot below), then I what I want to render is an input field which would consume a value coming from an API GET request and track change in state whenever the user inputs any new information in. I will also have a divider (

) and then the default text area of the editor that would also render API GET request data tracked by local state management mechanism. My question is geared towards whether MDX has a prop that can accept that input field in as part of the markdown ? (See the image attached).
My final goal is to have an email card component with an email subject section right below the Toolbar, a thematic break line and then the email body.
