Persistent Reference ID for a local document

When a file is uploaded to Decisions by dragging it from Windows Explorer to the Decisions designer environment web page, the file acquires a reference ID, and that reference ID is persistent and allows the document to be invoked from a flow.

Dont know how to serve the same purpose in a dynamic way. A new reference ID can be obtained with the "Load From Path" step, but it comes without achieving persistence, this association is not enough to invoke the file later from a new flow.

Then, in the case where a document is on the local disk and Decisions can access it, which is the procedure that allows the document to persist within Decisions and can be flow-operated invoking its reference ID?
