Well, since you got it, it'd probably be easier to do it the way you're doing it, but it's the same as (from within EAC) burning with a cue sheet, except instead of doing load cue sheet, you do "new" or something, and then just keep adding tracks.
Or you can just notepad an existing cue sheet and look at it, and change everything to the appropriate values.
Well, alright, maybe it's not that easy, but I'm a computer geek, so it seems pretty easy to me.
