Fira Code stylistic sets support?

Does iTerm support font options, like Fira Code's stylistic sets? Here is what I'm talking about. I don't believe this has everything to do with ligatures, as some are just replacements for certain characters.

Detailed steps to reproduce the problem:

  1. Enable Fira Code as your font
  2. In iTerm2 -> Preferences → Advanced → Drawing, set Improves drawing performance at the expense of disallowing alphanumeric characters to belong to ligatures. to No (instructions taken from link above).
  3. Type $, @, or & into the terminal, and see results

What happened:

The above symbols appear as normal Fira Code glyphs.

What should have happened:

The Fira Code alternate glyphs (viewable in the link above) should appear.
