Provide additional fields in Operating Systems record

We are designing an Enterprise Lifecycle map and along with that are identifying fields such as:
State of the OS - (Supported, Obsolete, Research, Transitional, Retired)
Disposition of the OS - (Maintain, Retire, Replace, Purchase)
End of life Date (Already Exists)
End of Support Date (Already Exists)
Extended Support Available? Yes/No
Extended Support Ends Date
Expected Life
IT Support Begins (When will IT begin deploying)
IT Support Ends Date (When will IT stop deploying)

IT would be awesome to have these fields in the OS record for populating and reporting
