Because a listing is synced with what you have listed on the sales channel's platform, you can update the SKU directly on the platform (i.e., Etsy), and Trunk will pick up on it like magic.

Changing a listing's SKU can cause it to be linked to another product within your inventory, depending on the sales channel's settings, or to stop syncing with the same listing on other platforms.

There is currently no way to edit the listing directly on Trunk, but this feature is coming soon!
