Is it possible to generate typescript declaration files (.d.ts) in both cjs and esm formats when bundling a typescript library?

My package.json looks like this

{
  ...
  "source": "./src/index.tsx",
  "main": "./dist/index.js",
  "types": "./dist/index.d.ts",
  "module": "./dist/index.mjs",
  "exports": {
    ".": {
      "import": {
        "types": "./dist/index.d.mts",
        "default": "./dist/index.mjs"
      },
      "require": {
        "types": "./dist/index.d.ts",
        "default": "./dist/index.js"
      }
    }
  },
  ...
}

and here's the output

I want to generate both an index.d.ts file and an index.d.mts file at the build time, but I couldn't find a way to do this, my current workaround is to use a script that copies *.d.ts files to *.d.mts files in the dist directory after the build.
