We're implementing custom segments and would like to update entities and historical transactions. I can handle the majority of it via CSV imports but will need to update some via script (e.g. item fulfillment). Is there a clean way to update item fulfillments in place and avoid situations where we get the Please configure the inventory detail in line [#] of the item list error? I'd love to just be able to set the segment, save the record and move on. My gut says there isn't a clean way but I thought I'd throw it out here.
