Permanently hide a field, even in expanded view. Especially the linked tables column

Please create an option to permanently hide a field. Especially the fields that are apparently REQUIRED when linking to another table. It would be great if the table that was linked FROM didn’t get clogged with that annoying field.

For example, when linking to different tables, a field is created on the original table. Yes, this field can be hidden…in the grid view. However, in card view, when a record is clicked (expanded) to see more information, that field is shown.
