Help with a cap ebb and gro bucket system

I want to use the cap ebb and gro controller bucket and 8 two gallon buckets and build a system running 4 reservoirs 1 for every 2 buckets so that I can setup my perpetual harvest. My thought is that if I were to use 4 5 gallon buckets as my reservoirs and each buckets uses 2 pumps that master controller bucket will operate to fill and drain the 2 gallon buckets on each individual reservoir. Is it possible to run the system described with just 1 controller bucket for the entire system and have multiple reservoirs controlled by that buckets timer mechanism.
Thanks in advance for any help
