Would be great to have the ability to group CMS collection fields into sections with custom headings similar to how the current "Basic Info" and "Custom Fields" and are separated visually. Or even just the ability to insert a heading label between fields and we could rearrange accordingly under those labels.

For example: We have a CMS collection for case studies that uses nearly all 60 fields with a lot of repeating, similar fields for images. We do currently use prefixes but having the 60 fields but the ability to add a heading and groupings would create a faster and better UI/UX.
