USB 8451 - SPI Communication with 4 IC's - C++

Hello,

I am about to use Melexis 90316 IC's: 4 of them. I am communicating using the SPI framework with the USB 8451. Figure 17.4.2 of the datasheet I have attached essentially shows how I would connect the chips. Here's the problem: I am looking to acquire all the data at the same time, but the 8451 only has one MOSI and one MISO port. Is there a way to setup the DIO channels on the other side of the device to acquire the MISO data continuously and in parallel from all 4 chips? Additionally: I have just begun to familiarize myself with the C++ API: do I have to run everything as a script to make things go faster? How does one do continuous streaming of input data without constantly having to query each IC?

Thanks for your help!
Nathan
