Roadmap Planner Macro: "Quarters" Granularity

We are interested in using this for ISP contract terms. In general, the terms of our contracts are 3 years, but it would give us visual tracking of those terms which need to be prioritized for re-negotiation each quarter.

Eg of what we manage today in a spreadsheet:

Since the decision on the granularity is mutually exclusive with the drop down, would be great to see something that allows us to take advantage of the pre-configured 5 year time-frame.

Thanks!
