Possible to buffer DI with 6221 board?

Question

http://sine.ni.com/nips/cds/view/p/lang/en/nid/203867
Just curious if with DAQmx I could monitor multiple DI lines (for instance Dev0/port 1/line0:7) at a rate of 100 hz, but buffer the reads so in software I only had to loop at, say 10 hz and could read an array of 10 samples at a time. So, I'd get a 2d array of 8 lines (rows) by 10 columns (samples). Or are DI reads purely software timed? Basically, the DI equivalent of N channels, N samples for analog input.

Thanks, Felix. After you mentioned waveform, I went and looked for digital waveform examples and found correlated dig read with counter. That VI looks at a digital waveform of lines 0-3 on a single port, so I pretty much just used that logic. I will mark a solution once I verify this truly does what I want. Also, I believe we do use the PFI lines, but only at 1 hz so we can do single point in software.
