I understand that it's possible to create a map pattern with fills (https://www.highcharts.com/demo/maps/pattern-fill-map); however, this is overkill for most applications. I am also aware of being able to change the null color for regions with null values (plotOptions.series.nullColor).

However, I would like to request a quick and easy way of setting a hatch pattern for null regions without going through all the rigamarole of specifying an image url—something as simple as plotOptions.series.nullColor = hatch, for example.
