eBay Multiple Rate Tables & Guaranteed Delivery

In the Shipping Column group you will find the "Domestic Rate Table" column.

First time users need to click 'Fetch your Rate Tables' to initiate a new authorisation flow in a new window to use this feature (required by eBay) - click on any row drop down to show the "Fetch your rate tables" button.

Once authorized - the list will be populated with rate tables (including any eBay Guaranteed Delivery eligible shipping rate tables). 

You can then select the appropriate rate table from the drop down list.  This can be applied individually or in bulk (using search + filter if necessary).  

Remember to save using the white eBay button at the top.
