Import vaadin-lumo-styles into a css stylesheet

I guess this is a CSS question more than a Vaadin one but I have little experience with CSS and I can’t figure this out.
I have made some components using LitElement that each have their own shadow root, and a css file with shared styling that I import in all of them. Now I also find myself importing some of the vaadin-lumo-styles into most of them (mainly the utility one). Is there a way to add this import to my shared css file so I don’t have to remember to add it to every component every time?
Or is there a different way to achieve this?

Unfortunately the Lumo style sheets are all packaged as JavaScript/TypeScript imports/modules, and can’t be imported into .css files. But if your shared style sheet is also a JS/TS file, then you can import the Lumo style sheets into that.

That makes sense, thanks
