Yes. (

As for altering the steps, that *may* also be doable, not sure exactly if there's a safety check on that, or if the copy of the config in the userstore is actually the one being used. (there's a config file hidden somewhere in the system/ folder).
Can't do much about Topaz/PDF with their crappy embedded fonts though, so... Avoid them like the plague that they are, or try to convert them. (It's a tad tricky for the Topaz files, but AFAICT it should be doable with a bit of effort and the right tools).
