Theme builder Display Conditions - "Not by elementor"

Prerequisites

• I have searched for similar features requests in both open and closed tickets and cannot find a duplicate.
• The feature is still missing in the latest stable version of Elementor ( Elementor Pro )

What problem is your feature request going to solve? Please describe.

It would be nice, if you could create a global template for single posts, as a fallback template.
Meaning that the template should only be used, if the post is not already build by elementor.

Describe the solution you'd like

In display conditions, an option to exclude single posts build with elementor, so you can have a few single posts that is not affected by the template. or use the template as a fallback for posts not build with elementor yet.

Describe alternatives you've considered

Excluding by tag, excluding by id etc. but that is not automated.
