Continuous query and time stamp

Hi, i use influx 1.8. i have a continuous query which calculate the mean of values every hour.
The timestamp of the mean calculated by cq, as reported in documentation, Is the start of period: for example, the mean that has timestamp 16:00, Is the mean of values from 16:00 to 16:59.
Is It possibile with a trick to change this? I would like, in the described example, to show 17:00 (or 16:30 like a mean) In alternative, Is It possibile to show want i’m saying in grafana by an overide?
