Storing archive files through ArchiveLink

I have searched for a guide of how to store archive files created through transaction "SARA" in a 3rd. party storage system through ArchiveLink.

I have a good understanding of how to do the archiving through SARA using the FILE-transaction. I found somewhere that the logical filepath should be set to something like "<F=ARCHIVELINK><FILENAME>", but where and how do I specify the archivelink-parameter?

We want to archive workitems using the workitem-object and has done so in test by placing the file on a share, but now we would like to place the archive files through ArchiveLink.
