Set product/line item start date as days from close date
It should be possible to set a line item's or a product's start date as X Days/Weeks/Months from a deal's close date.
For products: The default period could be configured in the product's description just like the default term.
1- The salses don't have to update each line item's start date when a deal is pushed: it is updated automatically when the close date is changed.
2- The sales don't have to look elsewhere for the standard delivery times: Product managers provide the default delivery schedule in the product definition and it is automatically applied to new line items.
