Set a date property as "x days after" day of step

Is this being developed for deal based automation as well?
I would love to have the capability of automatically calculating projected dates from an initial date stamp of a deal property. This would be an invaluable thing for since we are a sourcing company and we have to know our dates from production to delivery. An adjustment at the anywhere on the timeline would have a compound effect on the entire project timeline and manually adjusting these dates is a tedious process.
