Show Specific Folders and Recent Folders in Default Folder

Quality of Life Suggestion:

We have the option to select Recent, All, or Specific folders for the Default folder list.

Might it be possible to select both Recent /and/ Specific folders for the Default folder list?

The issue does not name a file, test, or entry point. Start by tracing how the Default folder list handles the Recent, All, and Specific folders selections, then identify the existing tests for that preference. Done means the default list can combine Recent and Specific folders without breaking the other choices.
