I agree whole-heartedly with this. It boils down to my sales channels having the same SKUs but different item names. For example, my Amazon and Ebay item names are lengthy as they add to the description, but on my website they're short. But on ShippingEasy it displays this really long item name on the PackingSlip which is no good. Also, this makes the Pick Lists think the items from different sales channels are different and, thus, doesn't combine them. This makes the pick lists really complicated when I get sales from different channels.
It's not feasible, nor desired, to change the item name to the same thing on each sales channel.
The easy fix here would be to add what the OP requested: have an option (a checkbox or something) on each product in the ShippingEasy catalog to override the Item Name. For example, on an incoming order, look at the SKU from that order, and if it matches a product in the ShippingEasy catalog, and that product has the "Overrride Item Name" selected, it pulls the Item name from ShippingEasy rather than from the sales channel.
It seems to me that one of ShippingEasy's underlying problems is it's reliance on the Item Name as the unique identifier, and not the SKU. I know you guys created an option to create a SKU Alias, but what we really need in this case is an option for Item Name alias
