Copying features from font to font

I apologize if this has been covered before. I searched but couldn’t find anything.

-you have a font family with several styles;
-otf features are identical in all of the styles;
-you’ve completed the first style, which contains several custom features;

Is there a way to copy all of the otf features from style to style, or do you have to copy and paste each feature individually?

Cmd or Shift-select them in the sidebar & copy.
Go to the other font’s Font Info > Features, click in the sidebar & paste.
