SagePay - Form or Direct?

hi guys,

we currently run the sagepay “form” as our payment processor, just wondering if we where to switch to the sagepay “direct” option, would we still need to login to the sagepay admin interface to release payments or can this be done directly via cs-cart’s back end.

for example, if you update the order status to processed, would this release the funds for the order automatically, therefore no need for us to login to sagepay admin interface? its not a big deal but would simplify admin and speed things up if this is the case.

ps. we currently use transaction type “deferred”
