Hi ranone,
To be honest: I don’t know but would not know how to achieve that. The extra fields are saved in these attribute names:
_woosea_brand
_woosea_gtin
_woosea_mpn
_woosea_upc
_woosea_ean
_woosea_optimized_title
_woosea_condition
_woosea_age_group
_woosea_unit_pricing_measure
_woosea_unit_pricing_base_measure
_woosea_installment_months
_woosea_installment_amount
_woosea_cost_of_good_sold
_woosea_multipack
_woosea_is_bundle
_woosea_energy_efficiency_class
_woosea_min_energy_efficiency_class
_woosea_max_energy_efficiency_class
_woosea_is_promotion
_woosea_custom_field_0
_woosea_custom_field_1
_woosea_custom_field_2
_woosea_custom_field_3
_woosea_custom_field_4
_woosea_exclude_products
I guess you should be able to retrieve the attribute values for them via the product object.
Best,
Eva
