Autocascade release dates

As a Product Manager, I want to be able to add a standard release cadence and if one of my releases gets delayed, the rest of the releases get pushed back as well. For instance, if we have standard 8-week release schedules and one gets delayed by 2 weeks, I'd like for all my remaining releases to be automatically pushed back by those 2 weeks to save me from having to 1. calculate what date is 2 weeks later, and 2. having to do this for every future release.
