Where should the lead time be defined?

Summary:

There is a requirement to account for a post-production lead time such as a cooling-off period or buffer time. Where should this lead time be defined? Should it be incorporated within the item attributes, or is there a separate configuration available specifically for post-production settings? Is there a way to define this within the item attributes so that it is automatically factored into the planning run, ensuring the buffer is embedded in the timeline?
