A. To streamline the process, first, ensure that you are logged into your account. Navigate to your wishlist and look for an option to 'Add to Basket' or 'Transfer to Basket' next to each item. If this option is not available, consider selecting multiple items at once if the app allows it, and then look for a bulk action button to add them to your basket.

B. If the app does not support bulk actions, you can manually add items to your basket one at a time. To make this process quicker, keep your wishlist open in one tab and your basket in another, allowing you to switch back and forth easily.
