Mongoose schema of array of object ids of different types, how to poulate?

Question

I am developing an app using the MEAN stack, and I would like to create a schema as follows:

var UserSchema = new mongoose.Schema({
    name: String,
    active: {type: Boolean, default: true},
    services : [{type: mongoose.Schema.Types.ObjectId}]
});

mongoose.model('User', UserSchema);

I would like the services to be of different types, with some functions that are present in all of them, so that I can iterate through them and call a function such as service.getStatus();.

Is it possible to automatically populate the services array using Mongoose's populate() function?

Thank you in advance for the help.
