Can text font in Appearance settings specify "light" version?

The Text Font setting allows me to specify SF Pro Text, but it’s a little too bold on my display. Is there a way to specify SF Pro Text Light? It’s on my system, but Obsidian only sees the main font families. Would I have to do this via a CSS snippet? Can you refer me to an example for the current Obsidian reading/editing modes? Thanks.

My suggestion is to go ahead type the full name of that variant font and simply click ok/save. I’ve experienced that the input field didn’t properly cache the font list. But i enter anyway and the font is reflected in the app notes.
