You can change the settings selection for a target marketplace by following these steps:
Go to the Build International Listings tool.
If you have set up a second source marketplace, you will need to select the source marketplace for which you want to add a target marketplace using the marketplace switcher at the top of the page before you proceed.
Click the Edit button to the right of the source marketplace.
Follow the workflow to create a connection using Build International Listings to edit the settings for the target marketplace for the selected source marketplace.
Processing and creation of offers might take up to 4 hours to complete. After the target marketplace connections have been updated, a Status Report will be generated and available on the Build International Listings Manage Connections page. You will receive an email informing you that the process is complete, with a summary of the results. Find out more

Note: If you are using the self-fulfilled method, it is recommended that you review your shipping settings for each marketplace to ensure that you are setting the rates that meet your requirements.
