I have this really basic SAPUI5 application created from the template available in SAP Business Application Studio.

I have defined a custom resource in the manifest.json which executes a javascript function:

{
  "sap.ui5": {
    "resources": {
      "js": [
        {
          "uri": "lib/myFunction.js"
        }
      ],
      "css": [
        {
          "uri": "css/style.css"
        }
      ]
    }
  },
  "...": "..."
}

Is there a way to dynamically define the resource to be used in the application bootstrap?

For example, in my "lib" folder, I have different *.js files:

Is there a way to choose a single *.js to be used?
