How to add Additional Settings block in Schedule & Details

Our organization is running a LMS portal using Open edX from long time and it has tutor version on 3.11.0 . But our organization wants to build new Portal with tutor 15.1.0 and they want all the features which are there in old portal to be implemented in new portal with some additional features. Now the problem is previously who built the platform are now not available they have added one features where we in CMS instructor can specify the type of Course in Schedule & Details page in settings and that filter is shown in CMS home page and also Students get to see those as different Type of course. I’m finding difficulty in implementing that feature. Can someone please help me with this??
