Import to Required Destination Folder Structure

We are using "Unique Subfolder Names" option and setting it to use the "File Name".

Requirement is to import 2 PST files from different source file locations.

We renamed these source files to be the same filename.

When ingesting, the emails from the source files are placed in separate folders, example "Filename" and "Filename 1".

We want the emails from both source files to be placed under the "Filename" folder.
