How to mix Angular Elements with the "ng g library" approach?

As you know, the "ng g library" approach helps us with the creation of libraries of reusable components. But what if I wanted those components to be compiled into web components... through the support of Angular Elements? Not only that but also that each component from the lib was to be compiled into its own folder or JS file. How to configure a dev environment that would allow me to achieve that?

For example:

If I create a Lib and add a custom component, I know that I can compile it, generating a series of folders, such as esm5, esm2015, fesm5, etc. Now, the question is: How can I add, let's say 30 custom components to my lib, and then when I compile, it will create a folder for each of them containing the Web Component version of them... as if Angular Elements went through my lib of components and generated the Web Components version of each of them.

Like this:

lib/
lib/custom/comp1
lib/custom/comp2
lib/custom/comp3
lib/custom/comp4

Turning into something similar to:

Dist/
Dist/custom/
Dist/custom/bundle
Dist/custom/esm5
Dist/custom/esm2015
Dist/custom/comp1_web_independend_component_version
Dist/custom/comp2_web_independend_component_version
Dist/custom/comp3_web_independend_component_version
Dist/custom/comp4_web_independend_component_version

I also requested for Angular CLI team to help with that:
