Is there a way to handle .pcss extension files as postcss?

[NeroMorto]

Now I'm getting error:
You may need an appropriate loader to handle this file type. **/*.pcss

.pcss is not a commonly used ext. It is recommended to using.css instead

I know( But it what it is. There are many many .pcss files in project, which contains postcsss and .css with "native" css.
Tried several options, but nothing is working properly.
Thx for reply anyway.

Actually it is very easy to support .pcss in Rsbuild, just adding the following config to modify the CSS rule:

export default defineConfig({
  tools: {
    bundlerChain(chain, { CHAIN_ID }) {
      chain.module.rule(CHAIN_ID.RULE.CSS).test(/\.p?css$/);
    },
  },
});
