2. Navigate to the Cart tab.
3. In the Product source field, select the Select manually option.
- Note: Selecting this option will activate the section for manual product entry.
4. In the Products in cart section, use the product insertion tool (the cart builder) to search for and add the desired products, specifying quantities and variants if necessary.
5. Once all products composing the cart have been defined, complete the wizard and click the save button to apply the changes.
