Figma - Change font family on all instances

Goal:
Change font family, and apply new font family to all instances.

Ex:
On the image bellow, the Open sans text is set as a component, and the weights, are set as an instance of the component.

Then I wanted to change to another font family, and have the instances reflected that change, showing the new font family with corresponding font weights:

Challenge:

If I set everything as font styles (headers, body, etc), then I need to manually one by one when I want to test a new font.

That is why would be convent to have a master component that sets the font family and passes that to all typography system.

Question: How can I add instances that change according to the font family?
