The multi-floppy is usually the icon of save all, not "Save as...". Looking on internet, I see that the "Save As..." functinality is indicated with a floppy with a pencil, or a a floppy with "...". Something like this:

Now the save as icon is a floppy disk with an upward arrow, during the development of the new homepage was proposed a double floppy disk but it has a save all meaning.

We should found a new icon for the Save As/Copy process
