Generate Speech and Force New?

Am I missing something? I am new to audtion so I fully accept that possibitity. I am having two issues with Audition's Generate Speech Function:

1. I am using largish text files, so each time I open the Generate window, it has to told the previous, completed text file into the editor, even though I am going to delete and add a new one. This is a laborious waste of time. Is there a way to a new Generator window with each open?

2. I frequently find that the AI does not translate a word or sound as expected, so I must edit it. If I open the Generate window it is going to reload the entire set text sequence, wasting valuable time, and dropping most of the effects I have applied to the file. Is there a way to edit the text without this happening?

I feel like I must be missing something obvious here. I am guessing the expectation is to not use large files but dozens of small files, but that just does not seem efficient. Though, granted, it anything would have to be more efficient to than the zero product after 3 hours of work I have at the moment.

Please advise... All comments welcome.
