Changing month order in gg_subseries() from default calendar year to financial year starting July

[Cecil_Peak]

Is it possible to change the month order in gg_subseries from the default calendar year to a financial year, starting in July, i.e., so that the months run along the x-axis, "Jul", "Aug", "Sep", "Oct"..., instead of "Jan", "Feb", "Mar", "Apr", etc.? Many thanks.
