You want to leverage the automated optimization feature for the majority of line items in an order, but you do have a specific need for spend on one line item. Which of the following is the best solution for you?

The best solution is to turn on "automatically optimize line item budgets" and then opt out the specific line item that requires a fixed spend. This approach allows the majority of your line items to benefit from automated optimization, which dynamically allocates budget to improve performance across the order. Simultaneously, it ensures that the one line item with a specific budget requirement is not affected by the automated system, giving you precise control over its spend. Turning off the feature entirely would negate the benefits for all other line items. Allowing all line items to be optimized would override your specific spend requirement for that one line item.
