[TYPO3-english] extbase DateTime property mapping error in 6.1

[Domi]

Hi,

after searching the net I found an old post about this issue and could 
solve my parsing with additional code in my initializedAction():

// this configures the parsing
if (isset($this->arguments['client'])) {
$this->arguments['client']
	->getPropertyMappingConfiguration()
	->forProperty('dateOfBirth')
	->setTypeConverterOption('TYPO3\\CMS\\Extbase\\Property\\TypeConverter\\DateTimeConverter',
\TYPO3\CMS\Extbase\Property\TypeConverter\DateTimeConverter::CONFIGURATION_DATE_FORMAT,'Y-m-d');
		}

As I have more then one DatTime obect, is there a possibility setting 
this date format in an easier way, or is this the way to go?

Thanks for reading,

Dominic
