Is it possible to auto-import BEM blocks in webpack?

Question

BEM

Let's say I have a bunch of blocks and the same bunch of pages... How do I create entry points for them? For each page to register imports? Is it possible to auto-import BEM blocks that are used on the page? Is there any loader for this? Or is it all manual?
Now I'm using this script:

let files = []; 

function importAll(r) {
    r.keys().forEach((s, i) => {
        files[i] = r(s);
    });
}

importAll(require.context('../blocks/', true, /(\.less|\.js)$/));

But it imports all blocks at once
