Collective Retail need Shipping Cost report paid to supplier

[fritsh]

All it appears that within Collective, the COST we have as Retailer for the Shipping Charged by Supplier and debited from our Payouts - which we need to account for as a Cost of Shipping (and offset the Sales Revenue received) that there is not reporting or exporting capability in Collective to obtain this as total for a given period, or if we could export details to easily sum up. 

Shopify advises to manually sum up the shipping details from the Collective Dashboard Order Payments

- Given the volume that is really no Practical Solution. 

Collective is able to REPORT the COST on the Sales Report - WHY not also the Shipping Cost on the Supplier Order? 

Shopify - any Solutions, insight or upcoming Developments to address this?
