Need to diplay gantt chart in Government Fiscal Year format


I am using the vXiz gatnt chart. I want to display the dates that  I  dates that I enter for the start date, end date and milestone to display in the column header in government fiscal year as listed below:

For example, the United States government Fiscal Year 2021 is:

·         1st quarter: 1 October 2020 – 31 December 2020

·         2nd quarter: 1 January 2021 – 31 March 2021

·         3rd quarter: 1 April 2021 – 30 June 2021

·         4th quarter: 1 July 2021 – 30 September 2021

I am able to change the Fiscal Year – Starting Month to October but the headers do not reflect the govenment fiscal year properly. Fiscal year Quarter 1 from  October 2020 – 31 December 2020 should have the year as the following year. Govenrment fiscal years for Q2, Q3 and Q4 will be associated with the current year. I would like to see this in the column headers as the Quarters are but would like to first line hearder as governement Fiscal Year and the subheading in quarters. It appears that the years that are displayed in the header line are calander year and not the government fiscal year but the quarters are in goventment fiscal year.
