Transcription Dictionary editing

Is there a way to edit user added words that are part of the local Transcription function outside of Premiere, as in a text file? If so, where is the file located?

Secondly, (and related), in English any time the word "pounds" is translated it is given the British monetary symbol—which is hardly ever used in my transcriptions. This is another reason I would like to be able to edit the dictionary by hand.

Thank you.
