Option to Keep Task Dates When Copying to New Project

When copying one or more tasks from one project to another, there should be an option to keep all the original dates.

Use case: 10 tasks exist on project A with all their dates set correctly. We need the same 10 tasks to exist on project B (that has already been created). We want to be able to copy the 10 tasks from project A to project B and keep all the original dates. Right now, the dates on the tasks once copied to project B all reset based on project B's planned start date.
