Howdy ! (it's me, Flowey, Flowey the flower ! *ahem*)

So someone gave me a rather interesting link who leed to a site with almost all of the in game icon we can find.

My question is: is there any way to use the set 1 of the job icon as a macro icon? I never saw them and never heard of them. But it seems that all 2.0+ jobs are missing, so I'm guessing this was 1.0 icons.

If so, is there any way to use set 4 or 5 as macro icon? I would appreciate so much. Because I'm using job's crystal icon for my gears' shortcut but it make the icon bug each time I change job because the crystal is not is the same place anymore :T
