I'm working on a music catalog.
I have a Post Type called Track
I have a Post Type called Composer
I have a Post Type called Track Composer, which I use to create a many to many relationship between Track & Composer.
Now I want different Users to be able to enter data independently of each other and only see the data that they authored. I setup my Access privileges and that appears to work fine. As you can see in screenshot 1 (side by side signed in as Shie, which is an admin vs. Testy Testerson, which is a contributor), my Testy Testerson user can only see Test Composer and no others.
However, when Testy Testerson edits a Track and goes to attach a composer to the Track, Testy Testerson can see all the composers in the selection menu, not just Test Composer. (screenshot 2).
Is there a way to make it so that Testy Testerson will only sees composers s/he authored in the selection menu? In other words - can the popup only show the composers Testy Testerson can see in the Composer Post Type?
