Because the dashed line border in a polygon fill style does not work well at certain scales, but it cannot be given a custom dash pattern, I often instead give it No Pen on the border and instead add an Outline: Simple Line with black colour and custom dash.

Then I categorise the style with different colour fills, but it gives the same colours to my custom-dashed Simple Line. To remedy this, I have to amend the line colour on each category separately. If I then change the fill style for the layer, I again lose my black colour on the Simple Line and again have to amend this for each category. I can do a work around with a saved qml file in Notepad++, using Find on the relevant lines of xml and manually changing the colour values for each category, then reloading the style, but even that way is a faff.

Therefore, I would like to request either to be able to put a custom dash on a fill border, or to make it leave the Outline: Simple Line colour alone when I change the Fill Style for the categorised layer, so it categorises only the fills, not the simple line. If possible, this would be great in the current LTR, or otherwise a future one.
