This functionality is currently not an officially supported capability of the FaderPort 8 and FaderPort 16.
There may be some basic functionality available depending on the DAW. For instance using the FaderPort 8 and FaderPort 16 in MCU mode would allow to setup another FaderPort 8 unit as a Mackie MCU extender. However, being that this is not an officially supported setup in current firmware Presonus would not be able to provide assistance in regard to technical issues/difficulties.
