Make "selling channel adjusted quantity" a field for line items in orders.

We would like to be able to target orders/line items whose quantities have been adjusted by the selling channel. Having this field targetable by automation rules or external integrations (like Zapier) would be extremely helpful for us for keeping track of order changes and cancellations. Orders now display which items have been seller-adjusted and a summary of those changes within the order page, but there is no order field for that that is filterable or targetable.
