Alarm clock on Uniti2

Hi
I am a new purchaser of a Uniti2 from an approved retailer   (I am behind/slow but it was an ex display model ).

I realise this question has been asked before but, previous threads are closed:
Is there any way at all of adjusting the length of time that the alarm will go on for?
If not, I am hoping it isn't too late for Naim to address this issue in their next update .
