Is there way to load css styles from an external url?

For example, I have domain.eu but on my site in sub.domain.eu. I want to use styles which are stored in this domain. (These styles are common for all sites).

Example below is not working for sure.

"styles": [
    "styles.css",
    "http://domain.eu/themes/css/common.css"
  ],

Problem is that webpack is trying to bundle this styles. He cannot retrieve it. When I import it via css

@import('url');

It will not breakdown but it will have problem with missing assets like images or fonts.

Only solution is to add external css style into index.hml. But it is possible to set this value dynamically?

When we have three different themes which defines basic fonts, styles of headers and so on and I want to change it for example by route or basic select option element inside some component is there some kind of hack or something I can do it?
