Watching multiple directories with devtools `:watch-dir`

[Barakat]

I have SCSS files that are compiled to CSS and saved in the target/scssbuild directory. How do I make devtools watch this directory and hot-reload it too?

My shadow-cljs.edn so far is:

:devtools   {:watch-dir "resources/public"
                  ...}

resources/public contains files that are being tracked by git, and I would like to keep auto-generated files out of it.
