Can't set different content displays between view display items

If you create a view with the "Show:" set as "Content" and the "Row style options" to something e.g. Teaser on a views display (in my example a page display). Then create another view display within the same view e.g. a block or attachment. You can't then have a different display type for the page and not the attachment/block/another page

For example in the 2nd display if you changed it to be "Full content" it will also change it in the page display you created earlier.

The solution I guess would be to have what all other configurations have within views so you can select "All displays (except overridden)" or "This XXX (override)" Or just have this setting as always in dependant without the "all displays/only this display" option which I guess is how it is supposed to work currently
