I did a test development some years back to do a similar thing on the work order enhancement tab and it worked well (see image below)
You can use user-exit IPRM0003 to add a new "Enhancement" tab at the maintenance item level.
Then you need to create a new class type in the IMG for the maintenance item class, then integrate this into the enhancement tab above.
Talk to your ABAP Team.
