The Sparky list functionality is great if you want to save structured lists of products for easy access as well as letting you set product specific markup or margins.
You can select “Save to list from any item on the product catalogue”.
You can upload a CSV file or add products to the list from the product catalogue.
e.g. If am getting a great buy price on a powerpoint, I can jack up my margin/markup and use the list price for quoting and invoicing my customers.
