Master on/off adjustment granularity

I wish there was the option for selecting 1-5 second(s) master on adjustment and 1-5 second(s) master off adjustment as this would really help in my customers setups. Any adjustment time above 5 seconds would still maintain 5 second granularity. Having that fine tune in the 1-5 second range would make a big difference as having the lowest option of 5 seconds doesn’t really make this adjustment useful in my cases.

Thanks
