BLE confirmationReceivedCallback for Nordic nRF5x running GattServer

We are running a BLE GattServer and were hoping to use the the confirmationReceivedCallback. This is the callback that happens when a BLE client ACKs a notification. It appears the Nordic SoftDevice has this implemented (sets the event to GattServerEvents::GATT_EVENT_CONFIRMATION_RECEIVED), are there plans to implement for Cordio?
