Unable to edit panel header

Hi,

There is a panel header present on a few screens in our fusion application. On the employee's screen for Time and Absences, we wanted to rename the header to 'Leave Management' . I've tried making changes to the panel header using the Page Composer tool, but when I'd edit the Title and hard code it, it would overwrite multiple of the other headers as well.

Is there a possibility to achieve this using EL expressions?, please note this is for Responsive UI.

Thanks,
