Need better Android platform scopes

The project file supports 'scopes'. However These scopes are sufficient to handle android elegantly. Currently we can do

android {
ANDROID_EXTRA_LIBS = /home/Projects/vinscan/android/libs/armeabi-v7a/libiconv.so
}
(Or include ANDROID_EXTRA_LIBS outside the scope. However the libraries are limited to the architecture specified in the library.

It would be cool if we could use

android:armeabi-7a {
ANDROID_EXTRA_LIBS = /home/Projects/vinscan/android/libs/armeabi-v7a/libiconv.so
}
android:x86 {
ANDROID_EXTRA_LIBS = /home/Projects/vinscan/android/libs/x86/libiconv.so
}
Or even better
android:armeabi-7a {
ANDROID_EXTRA_LIBS = /home/Projects/vinscan/android/libs/$(SUBSCOPE)/libiconv.so
}
Where SUBSCOPE is after the colon in the specification.
