Out-of-the-box integration when using GET Method for SFTP Handler

Currently there is the SFTP Handler that allows users to create a connection between MAS Manage and their SFTP Server. The goal of the SFTP Handler and endpoint is to allow users to send and receive XML and Flat files from the server for use in Integration. See the following technote for more information: https://www.ibm.com/support/pages/how-configure-endpoint-sftp-handler

Configuring the endpoint you can choose whether to send files (SFTPMethod = PUT) or retrieve files (SFTPMethod=GET).
When configuring for PUT users are only required to have an External System configured that will send the expected output to the SFTP server, which works as expected.

However for the GET method, one requirement is that the specific file name that the Integration will be fetching needs to be stated. The issue arises as there is no way to provide this filename without some sort of customization (ie. an Automation script to invoke the endpoint or an Exit Class to add the functionality)

The need for these extra customizations adds an extra layer of complexity to the integration that not all users may have knowledge of, and also falls outside the scope for IBM Support. 

Instead there should be a simple way to configure this Handler/End point to be able to retrieve files without having to rely on extra customization. One end point we can reference is how the S3 Handler retrieves files from an S3 Bucket:

https://www.ibm.com/docs/en/masv-and-l/maximo-manage/cd?topic=properties-s3-handler

Users are only required to configure the Endpoint to point to their S3 Bucket, then there are out of the box cron tasks (LOADFLATOBJECT and LOADXMLJSONOBJECT) that are used to parse through the S3 Bucket for any new files. These will then pick up the files and place them into a queue to be processed into MAS Manage.
