Add a possibility to set default add-on values
For select box and radio add-on types, it could be beneficial to set a default option. This would be especially helpful if there are many required fields on a product, having default values already filled in would help decrease friction for the customers.
Alternatively, if an option is required but has no default value set, the first option from the list could automatically become the default one. I'm not yet sure what would be the best store owner flow to set this up, so comments will be much appreciated.
