Copy constructor using "initWith" for "productFlavors" and "sourceSets"

Question

With reference to this answer. Is it possible to create a copy constructor for productFlavors and sourceSets using initWith just like the one in the linked answer. That one worked great for buildTypes.

For buildTypes it was done this way:

debugfree.initWith(buildTypes.debug)

Is this possible for productFlavors and sourceSets as well?

awesome question, this is what I've been looking for. Looks like productFlavors have this trick to combine the flavor instead: https://mcmap.net/q/504933/-android-specific-gradle-product-flavor-combinations – Cuxhaven

Looks like it has been added in 2021, but somehow I can't make it work. See: issuetracker.google.com/issues/165642956 – Dustidustie
