Job Set for Supply planning Collection and Plan run for external source system

In the 21A release, Oracle introduced a feature that allows users to create a job set for the OPS source system, enabling Data Collections and Supply Plan runs to be executed sequentially within a single process flow.

In our case, however, data is collected from an external source system. We would like to understand whether there is a similar approach available for external sources that would allow us to:

1. Execute the "Load Interface File for Import" process.
2. Automatically trigger the Supply Plan run after the import process completes successfully.

While creating a Job Set, I do not see any option to select a job that can pick up files from UCM and run the collection process. The only available option appears to be the Collections Job Set, which is applicable only to the OPS source system.
