using trackby on object

API response returns an object with nested attributes for each option. How can I tell track-by to use an object property? i.e. track-by="attributes.language"

Example here: https://jsfiddle.net/fy18zy9b/3/

<multiselect 
v-model="value" 
:options="options"
    :multiple="true"
    track-by="attributes.language"
    :custom-label="customLabel"
    >
  </multiselect>

Sample options:

[
  {
    attributes: 
    {
      language : 'JavaScript', 
      library: 'Vue.js'
    }
  },
  {
    attributes: 
    {
      language : 'JavaScript', 
      library: 'Vue-Multiselect'
    }
  },
  {
    attributes: 
    {
      language : 'JavaScript', 
      library: 'Vuelidate'
    }
  },
]

Would be great to have any prop ‘customTrackBy’ (Function => String) like ‘customLabel’ so as to work with any nested object
