adding a particular font

My Kindle reader uses the Baskerville font.
Is it possible to add this font to the Scrivener list of fonts.

Baskerville is easily available on the internet, I would think; there is a free version Libre Baskerville available from Font Squirrel:

but I have no idea how well that equates to the version of Baskerville on Kindle.

Scrivener doesn’t come with fonts. Load it onto your computer and it should be available for all your programs that allow you to select your preferred fonts.
