Use Page List fields from template settings in admin search

[Toutouwai]

Short description of the enhancement

In the template settings it is possible to define the fields that are shown in Page List.

It would be good if there was an option for this setting to also apply to the admin AJAX search results so that pages appear there with the same fields that display in Page List. Otherwise it is harder for users to make the connection between pages they are seeing in the search results and pages in the Page List.
