How can the RRP be indicated in product comparisons (product exports)?

The RRP can be inserted in product exports as follows (in the example, the gross RRP is inserted):

{% set price = product.calculatedPrice %}
{%- if product.calculatedPrices.count > 0 -%}
    {% set price = product.calculatedPrices.last %}
{%- endif -%}
{%- if price.extensions.acris_rrp_price_price_struct is defined and price.extensions.acris_rrp_price_price_struct.getRrpPricePrice() and price.extensions.acris_rrp_price_price_struct.getRrpPricePrice().gross > 0 -%}{{ price.extensions.acris_rrp_price_price_struct.getRrpPricePrice().gross }}{%- endif -%}
