Can you enable attachments at individual custom content section types

Content

Hi,
My customer is using Enhanced Talent Profile.
We are using the seeded templates to create custom sections or Item Catalogs.

I understand there is a section called Attachments on the Talent Profile.
But that is a repository for all attachments in one section, which causes confusion to the users.

The business requirement is to be able to add attachments for individual custom content sections.
I checked in Page Composer/ Design Studio but didn't see any option there.
 

Any thoughts or ideas if this is achievable? Or if anyone has had a similar requirement and what solution did they go with?
