NI-6581 FlexRIO digital IO adapter module: can each I/O terminal be individually controlled?

I'm planning to get a NI-6581 adapter module for the FlexRIO FPGA card. I understand that each 8-bit data port can be configured as either input or output, however I'm wondering if it is possible to write (or read) different values to each terminals in a port (for example, writing 10101101 instead of just all 0 or all 1 to Port 0)? More specifically, for my application I'd like to have five ports (40 terminals) as output and one port (8 terminals) as input; and to control each terminal individually (data wise not direction wise). Is it doable with 6581? If yes, is there any example vi showing how to do that?

Thanks,
