Is it possible to add more cards to my system?

Single cards need the SBench 6 Professional license. Multiple cards need the SBench 6 Professional license and the SBench 6 Multi license for the star-hub. All cards inside one system are covered by the SBench 6 Multi license. You can add as many cards to one system as you like. All cards are covered by one SBench 6 Multi license on the system.
