Filter itemView list items, seperate from access filtering

[wchorski]

I am wondering if there is a way to show and hide certain items in the list view.

Scenario

Using the blog template. I have a Post schema that may be set to public, meaning accessible to any site visitor. The problem then occurs when an author reaches the admin UI and all public posts populate the list at http://KEYSTONE/posts

What I'm trying to accomplish

When a user visits the Keystone UI, they will only see their authored posts in the list view. This can be overridden if permission is allowed for the User to manage any post.

What I've Tried

In the itemView I'm able to accomplish logic that is close to what I'm looking for because of the item object.

Here is a snippet of my Post.ts Schema

...
ui: {
	hideCreate: (args) => !permissions.canManagePosts(args),
	hideDelete: (args) => !permissions.canManagePosts(args),
        // isHidden: (args) => !permissions.canManagePosts(args),
    itemView: {
      
      defaultFieldMode: ({session, context, item}) => {
        if(permissions.canManagePosts({session, context, item})) return 'edit'
        if(session.itemId === item.authorId) return 'edit'
        return 'read'
      },
    },
    listView: {
      defaultFieldMode: ({session, context}) => {
        if(permissions.canManagePosts({session, context})) return 'read'
        // if(session.itemId === item.authorId) return 'edit'
        return 'hidden'
      },
	initialColumns: [
		"title",
		"status",
		"dateCreated",
		"dateModified",
		"author",
	],
	initialSort: { field: "dateCreated", direction: "DESC" },
      },
},
...

Current result

In itemView this creates clear difference when the user visits a Post they are able to (or not) author. It would be even better if I could display some message like "Can not edit this post"

The listView falls short in 2 ways

1. defaultFieldMode does not have access to individual item objects so I cannot run logic per list item.
2. the hidden property only hides fields values and does not filter out per list item (that are in this case set to public but NOT authored by user)

Separate from access & permissions

Just to be clear, I'm asking for filtering separate from CRUD filtering. My CRUD filtering is working as intended and these public posts are accessible by the frontend the way I'd expect.

I am asking for some better user experience filtering that allows me to show and hide things in the Post list ui to certain authors that only pertain to them when editing said Posts
