Thank you for your feedback. To clarify, were you wanting to see the sales of each SKU by store in a downloaded report? Or, was this something you were hoping to see directly within the ShippingEasy application?
In terms of our existing product reporting, you are able to run each of our Product Sales Reports across all stores (which is the default) or alternatively you can specify the store you wish to review. You just need to select your store from the Store menu shown next to the Report Date Range on the Report Snapshot page.
The following support article provides some more information on our existing Product Sales Reports: https://support.shippingeasy.com/hc/en-us/articles/204295639
