In the Advanced tab of the sync settings you may add one or more dependencies by selecting the + button beside the respective text field or typing the dependency’s title.

When starting a sync item which has one or more dependencies that haven’t been completed, they are run first. As soon as all dependencies have completed successfully, the sync item will start running. If a dependency encounters some errors or is cancelled, the sync item will be delayed until the dependency is completed.

You may create dependency chains as long as they are not circular. For example, sync item A can depend on B which in turn can depend on C, but C may not depend on A. Sync items that would cause a circular chain are automatically disabled in the dependencies menu.

When starting a sync from the File menu, the main window context menu or the toolbar, you may hold the Option key in order to temporarily skip the dependencies.
