Cannot merge resolveRequest functions

[jasonlewicki]

Right now, if I have 2 or more configs that have a resolveRequest function, the one loaded last overwrites the previous functions:

const { withNxMetro } = require('@nx/expo');
const { getDefaultConfig } = require('@expo/metro-config');
const { mergeConfig } = require('metro-config');

const defaultConfig = getDefaultConfig(__dirname, {
  isCSSEnabled: true,
});
const { assetExts, sourceExts } = defaultConfig.resolver;

const customConfig = {
  transformer: {
    babelTransformerPath: require.resolve('react-native-svg-transformer'),
  },
  resolver: {
    assetExts: assetExts.filter((ext) => ext !== 'svg'),
    sourceExts: [...sourceExts, 'cjs', 'mjs', 'svg'],
  },
};

module.exports = withNxMetro(
  mergeConfig(defaultConfig, customConfig),
  {
    // Change this to true to see debugging info.
    // Useful if you have issues resolving modules
    debug: false,
    // all the file extensions used for imports other than 'ts', 'tsx', 'js', 'jsx', 'json'
    extensions: [],
    // Specify folders to watch, in addition to Nx defaults (workspace libraries and node_modules)
    watchFolders: [],
  },
);

withNxMetro has a resolveRequest function. If my customConfig needs one as well. How can I resolve this?
