lodash - Find object by match property in nested array

I'm not seeing a way to find objects when my condition would involve a nested array.

var modules = [{
    name: 'Module1',
    submodules: [{
        name: 'Submodule1',
        id: 1
      }, {
        name: 'Submodule2',
        id: 2
      }
    ]
  }, {
    name: 'Module2',
    submodules: [{
        name: 'Submodule1',
        id: 3
      }, {
        name: 'Submodule2',
        id: 4
      }
    ]
  }
];

This won't work because submodules is an array, not an object. Is there any shorthand that would make this work? I'm trying to avoid iterating the array manually.

_.where(modules, {submodules:{id:3}});

Lodash allows you to filter in nested data (including arrays) like this:

_.filter(modules, { submodules: [ { id: 2 } ]});
