How to add product abstract multi-store assignment?


Which importer command should import store assignment?


but it doesn’t seem to be used anywhere. What command is supposed to run this function? None is mentioned in

Even if we ignore the “separate step for store assignment import”, How to assign stores to the product? using

The key “store_name” was not found in data set.

Also, ProductAbstractStoreHydratorStep seems to support only ONE store, and that means we have to run importer as many times as we have stores even though all of the stores are listed in the json file?
