filter cleared to value

[SledgehammerPL]

Is it possible to clear date filter not to empty but exact date (today?)
My actual filter is defined:

public function listFilterExtendScopes($filter)
{
  $filter->addScopes([
    'test' => [
      'label' => 'My Label',
      'type' => 'date',
      'modelClass' => 'XXX\YYY\Models\Document',
      'conditions' => "xxx_yyy_documents.id IN (select id FROM xxx_yyy_documents WHERE ':filtered' >= document_date)",
      'default' => Carbon::now(),
    ]
  ]);
}

On first show - it filters Carbon::now(). Perfect.
If I change date - filters perfect.

But When I press Reset button it shows me all documents - And I want to set it to Carbon::Now()...
