How do I designate a target font so that the target file is ready for delivery after being generated in Studio?

Dear Studio 2015 experts,

I can't seem to find the place in Studio where I can specify the target font for a project.  The client wants the target Chinese files in a certain font, and they sent me the font to add to Word.

Is it possible for me to add that font to Studio so that I won't need to open each file in Word and manually change the font?  I looked under Font Mapping but have no idea how to add the font (DFHeiHK-W3) or if it is even possible to do this in Font Mapping, since the language variant (English to Chinese Hong Kong) is not listed, either.

Thank you so much for your suggestions.

Chunyi
