How can I set Paypal Express Checkout or Pro payment gateway to only authorize transactions and not capture the funds automatically?

The Paypal integration with Matukio is Paypal Express Checkout, Pro or both? It will allow to simply authorize the charge when a customer places a booking rather than capture the funds automatically?

Payment Gateways that Allow "Authorize Only"
[ul]
[li]Paypal Express Checkout[/li]
[li]Paypal Website Payments Pro[/li]
[/ul]
Is this feature possible in Matukio?
