Notification of a confirmed uplink message

Hi all,

On there is a description of a MQTT publication with application/[applicationID]/node/[devEUI]/rx topic refleting an uplink message sent by a device.
We have an aplication that is supposed to behave differently depending on uplink message having been sent in a confirmed (CON) or non-conformed (NCON) mode. However in the referred MQTT publication there seems not to be any explicit mention to the confirmed ou non-confirmed mode uplink message was sent.
Is there any parameter in this publication reflecting CON/NCON character of uplink message?
If the answer is negative, is there any expectation of a further version of LoRa network server to address this issue?
Thanks in advance,

Paulo Sardinha
