How to Change Milestone Dates to Durations?

[robebany]

I am working on a project roadmap and have created multiple cylindrical timelines for each of the stages of the project. Since the timelines include the dates, I am looking for a way to have each milestone show the duration of time versus the date itself. Is this possible?
