That's a different animal than a semi-automatic. A semi-automatic is what I call a level action, in reality a regular fly reel with a ratcheting device that allow retrieving the line by pumping the lever. I have never seen an automatic, like your Martin or a Perrine that had much of an adjustable drag system or room for backing.
