Perch Shop - Setting default product values for all products

  • Hi All,

    I'm wanting to set a default values for all products already in my Perch Shop and then update all the products once I've updated & uploaded 'product.html' file.

    I'd like to have all products 'requires_shipping' set to true (yes).

    I'd also like to know how I set dynamic fields to do the same i.e. <perch:shop id="show_productrating" type="checkbox" label="Show Product Rating" value="1" default="1">

    Many thanks in advance
