Adding more than one fonts as alternate

Dear Team,

We have predefined selected set of fonts that are almost similar to the ms tty fonts .
Now while creating the doc/docx I want to set the font name as
Calibri+Roboto.
Meaning, if Calibri is missing in list of system font on user system, use Roboto. I will bundle the font file in case of docx file.
How can this be achieved. Can you please share any code examples?
