Yes the Customweb Magento plugin is able to handle and flag orders which have been flagged for Manual review by the Peach Payments platform.
The module handles this status code 000.400.000 and 800.400.500 and marks corresponding transactions as uncertain in the Magento shop.
It is also possible to match a certain state of the order in the shop with this "uncertain" transaction status. Such orders will be set to this state and can be manually reviewed in the shop.
The particular status a flagged order would be set to can be modified in the Payment Method configuration as shown in the screenshot below:
