I want to split my package into sub packages for faster compilation, but I have some custom settings that I don't want to copy-paste 10 times since that makes editing them really annoying. Is there a way to inherit the settings from the main-package, or avoid repetition in another way?

I found this 2 years old post:
https://forum.dlang.org/post/wdkrsfjfbtnmpxcguwca@forum.dlang.org
It is mentioned that when using --combined the flags are inherited, but I also want to inherit the settings when not using that flag.

The settings in question are:
```
dflags "-dip1000" "-dip25"

buildType "debug" {
	buildOptions "debugMode" "debugInfo"
	buildOptions "betterC"
	buildRequirements "allowWarnings"
}

buildType "release" {
	buildOptions "releaseMode" "optimize" "inline"
	buildOptions "betterC"
}

buildType "unittest" {
	buildOptions "unittests" "debugMode" "debugInfo"
	dflags "-checkaction=context"
	buildRequirements "allowWarnings"
}
```
