Query Builder Issues (dots in columns name, resultset problems)

Hi, I have some issues with Phalcon query builder, issues are critical and I've tried many times to find a logical solution for them, but nothing.

First Issue

I think this is a bug! however...

I want get a column name like title as foo.title, look at sample code:

$options = ['...'];
$builder = $this->modelsManager->createBuilder();
$builder->from(['aircrafts' => 'App\Models\Aircrafts']);
$modelAlias = 'aircrafts';
$columns = [];
if($options['columns']) {
    foreach( $options['columns'] as $column ){
        columns[] = $column . ' as `' . $modelAlias . '.' . $column . '`';
    }
}

# sample query
# SELECT id as `aircrafts.id`, title as `aircrafts.title` FROM ...

Ok, as you know in mysql this query is valid, but seems phalcon does not offer any way to do this.

Backticks (`) in phalcon query builder cause query scan error, how could use dot (.) in phalcon columns name?

Second Issue

Query builder resultset issue

Sample code:

$builder = $this->modelsManager->createBuilder();
$builder->from(['seatmap' => 'App\Models\SeatMaps']);
$builder->join('App\Models\Aircrafts', null, 'aircrafts');
$builder->join('App\Models\Airlines', 'aircraft.airline = airline.id', 'airline');
// Set columns
$builder->columns('seatmap.*, aircrafts.*, airline.title');
// ...Execute Query...

query result will be something like:

    // Complex Resultset   
    [
        'seatmaps' => {
            'id': '...',
            'title' : '...',
            // ..
        },
        'aircrafts' => {
            'id': '...',
            'title' : '...',
            // ...
        },
        'title' => '...' // this is airline title
    ]

as you see, in this case I need title column from airlines table and all columns from seatmaps (seatmaps.*) and aircrafts (aircrafts.*) models. how its possible to get data in following format:

    // Complex Resultset   
    [
        'seatmap' => {
            'id': '...',
            'title' : '...',
            //...
        },
        'aircrafts' => {
            'id': '...',
            'title' : '...',
            //...
        },
        // title belongs to airlines, so i want it be a child of airlines object
        'airlines' => {
            'title' => '...'
        }
    ]

how can I do this, fetch all columns in their related object in query builder resultset?
