Similar to my previous idea: https://community.esri.com/t5/arcgis-pro-ideas/export-layout-accessibility-prefills/idi-p/1656726
I am using ArcGIS Pro 3.5.2 and I've recently started looking what ArcGIS Pro offers for exporting PDFs with accessibility metadata. For the "Accessibility" tab for the "Export Layout" tool with PDFs, I noticed that if I enter information in for the accessibility inputs in one project that it carries over what I input into other projects.
Here is an example where the metadata parameters that were prefilled from another project.

As an Idea: Instead of pre-filling the "PDF Metadata" parameters with previous filled information, I'd like it to be sourced from the Layout Properties Metadata.
- Title: Use Title from layout properties
- Language: Add a language metadata field to Layout properties
- Subject: Use Summary or add a Subject field to Layout properties
- Author: Use Credits from Layout properties or add an Author field to Layout properties
- Keywords: Use Tags from Layout properties or add a Keyword field to Layout properties
