No. Even on the final screen, add a new profile, enter settings on the popup form and save. Nothing. The new profile doesn’t show up anywhere. Any view, drop-down menu, any list, anywhere.
So instead I manually added a new .roboxfilament file to C:\Program Files\CEL\Common\Filaments\ with the setting I wanted to try. Then restarted Automaker, wrote that material to the reel (from the first screen) and went on printing.
