We should have a custom free text imput for Google base attribute.
Google now have several extra fields that can be added. Examples are Payments accepted, payment notes, Shipping, Tax and ....
It would be nice to have a custom free text that can be used for ALL products. i.e for Payment method or payment notes we should be able to select free text from Magento and enter free text such as “VISA, MasterCard...” to show for all products.
