How can I eager load a relationship directly to the parent with its own keys without loop?

Is there a direct way to eager load the relationships key values directly into the parent. I mean without storing it under a sub element?

for example:

$user = User::with('contact');

but instead returning this:

[
'name'=>'john',
'surname'=>'doe'
'contact' => [
    'phone' => '...',
    'email' => '...@...'
]

I want directly this:

[
'name'=>'george',
'surname'=>'doe',
'phone' => '...',
'email' => '...@...'
]

I could loop all users and place that value manually but I am wondering if there is a way that directly calls these from database. It would save me a lot of resource if there would be a direct way.
