Thank you for your request. You could create a roadmap like this using a custom pivot table. There are a couple different options for columns that you could choose from, including Release month or quarter, Feature month or quarter, or external release dates, or a custom field to capture specific time horizons. You can learn more about building pivot tables here.
This will allow a 0-3 months, 3-9 months, 9-18 months...
So there's less specific comitment from the development team and business.
