Hello,
You need to create the preset. Do you have any problems on this stage?
Then you need to go to the Typography > Advanced typography and uncheck “inherit” and then configure the styles.
You can change the font by means of the Advanced typography option, which allows you to choose the item from a drop-down or insert your custom CSS class. Please navigate to the Theme Settings > Typography > Advanced Typography.
Here is the documentation providing more detailed instructions: https://xtemos.com/docs/woodmart/advanced-typography-settings/
