Can before and aforementioned be used in a similar way to above?
Context: Say I'm writing a report, and would like to reference an earlier bit. If that earlier bit is in close proximity or follows immediately before, I might use "From above, we can see...". In this case, can I use "From before/aforementioned", especially if that earlier bit is at a certain distance away? Other examples are "As seen from above/before, ...", "... when applying [technical term], from before." -- [technical term] defined above.
I know that this isn't common and comes off as rather technical, I'm alright with that. My concern is whether using it as such is grammatically correct.
