PS 6000_RATIO_MODE_DISTRIBUTION available ?

I bought a 6403C picoscope used for a scintific acquisition. I need to use the hardware average downsampling mode in order to speed up data transfer thru USB3 to computer and in order to increase the vertical resolution. I would prefer to define my own coefficient(sinus cardinal like) instead of average for the internal FIR filter. So I need to use PS 6000_RATIO_MODE_DISTRIBUTION but in the documentation it is written page 37 that it has not been "implemented". So my first question is : when it is foreseen to be implemented ?
Thanks a lot !

There are no plans to implement this function at the present time so please contact support@picotech.com
