Two K8055 in parallel

I have connected two K8055 to a PC on which a DELPHI program reads and writes to/from the cards. It seems that I have to switch from one board to the other when I read/write alternating. The switching causes a significant delay, is there a way to have both card in parallel open for in/output ? (for avoiding the dalay in a fast data aquisition )
Thanks for good advice
