How load all assets in nx's lib used in many apps?

Question

I want to figure out how to add assets to nx angular lib and do not repeat this declaration in each app:

 {
   "glob": "**/*",
   "input": "libs/feature-a/feature-a-core/src/assets/icons",
   "output": "assets/feature-a/icons"
 }

I tried to use ng-packagr in lib and add "assets": ["./src/assets"] to ng-package.json but it doesn't work. I also tried import icons in lib's module by require.context from webpack-env and it also doesn't work.

Do you have any idea how to reduce this Boilerplate?

project.json of lib:

{
  "projectType": "library",
  "root": "libs/feature-a/feature-a-core",
  "sourceRoot": "libs/feature-a/feature-a-core/src",
  "targets": {
    "build": {
      "options": {
        "executor": "@nrwl/angular:package",
        "tsConfig": "libs/feature-a/feature-a-core/tsconfig.lib.json",
        "project": "libs/feature-a/feature-a-core/ng-package.json",
        "assets": [
         {
            "glob": "**/*",
            "input": "libs/feature-a/feature-a-core/src/assets/icons",
            "output": "assets/feature-a/icons"
          }
        ],
        "configurations": {
          "production": {
            "tsConfig": "libs/feature-a/feature-a-core/tsconfig.lib.prod.json"
          }
        }
      }
    },
}
