Output Directory

Is it possible to change the output Title of a book?
I change the books title on the conversion menu before hitting convert but when I look up the file in its folder the titles different to what i put in.
For example: I change the books title to 'Shield of Baal - 02 Tempestus' before converting, but afterwards it appears as 'Shield of Baal_ Tempestus - Braden Campbell'

Also it is possible to change the output folders, so that they go into a single folder rather than multipe sub folders?
