Append virtual static column/field in Laravel query?

Question

I have two scenarios to implement in my query from the same database table and show them in two different front-end tables. The problem is I need to implement both of the scenarios in a single query maybe with union.
I want to know if the current result belongs to scenario 1 or scenario 2. For that purpose, I want to add a virtual column in my query like scenario 1 or the scenario 2 to identify the results. Is it possible with laravel eloquent or raw query?

$a = orderModel::virtualColumn('scenario-1')

$b = orderModel::virtualColumn('scenario-2')
->union($a)
->get();

$result = $b;

Using Virtual Columns in Laravel - Accessors and Appends

class Order extends Model
{
    $appends = [
        'scenario'
    ];

    public function getScenarioAttribute()
    {
        return $this->fields_one . " " . $this->fields_two;
    }
}
