How to change the fields of a related list?

Hello,

I’ve got my project tasks and we’re using notes.
So notes are related to project tasks and their titles are being displayed just fine.

Now I’d like to display the body / Note itself in the list beside the title.

I’ve tried to add the note to the list view of Notes - but that didn’t change anything under my project tasks.
How to accomplish that?

Thanks,
Chris
