Although the encoders seem to be like volume knobs they are just a sets of switches.
So the BCR doesn't need to have an Analog to Digital Converter (ADC) to read all of its inputs.
The BCF, on the other hand, has analog faders to read so it needs a ADC.
As it has an ADC, the designers allow the pedal to be analog.
Perhaps if you explain what you are trying to do, there might be a way to do it.
All the best
