It is impossible to connect both to appear as a device with twice the number of channels. However, you can use both in the same program, which means there will be two buffers to manage. The data buffers can be synchronized if you use the clock from one device to clock the other device. Configure both using the AInScan function. Information about this function is in the UL Help document. Configure the first device to scan the channels, and when it begins, the scan clock will appear on AICLKO. Configure the second device to use the external clock scan option. It will wait until the clock appears before it begins. You'll need to configure the second device first; otherwise, the clock could run before it is ready. Using a short wire, connect AICLKO on the first device to AICLKI on the second.
