I came across a nice little solution in copilot X and copilot 365/pro for including and referencing custom instructions to add behavior/formatting support to copilot (e.g. edit mode, article writing mode, documentation writting mode etc.)
How do you get copilot to use these instructions? Can you define a “default include” somewhere?

<whatever my request was> ```
