How do you center ALL columns ? Wildcards?

[vesper8]

Right now I'm doing this silly thing:

    public function styles(Worksheet $sheet)
    {
        $styles = [];

        $styles[1] = [
            'font' => [
                'bold' => true,
            ],
            'alignment' => [
                'horizontal' => \PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER,
            ],
        ];

        foreach (['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'L', 'M'] as $column) {
            $styles["{$column}1:{$column}1000"] = [
                'alignment' => [
                    'horizontal' => \PhpOffice\PhpSpreadsheet\Style\Alignment::HORIZONTAL_CENTER,
                ],
            ];
        }

        return $styles;
    }

Surely there must be a way to use wildcards or apply a style to all cells/all columns/all rows?
