I/O setup for Pro Tools 11 and Presonus 16.4.2 AI

Here is what I want to do: Record 16 individual channels from my 16.4.2 AI to PT11........No problem, does it easy 1:1, 2:2, 3:3, etc. What I want to do is play back the recorded audio through the respective channels (1:1, 2:2, 3:3, etc) and be able to control it from the board, not just from the computer screen. So, I set the I/O Inputs up as described and also the I/O OUTPUTS to Main Output (channel 17/18 of the 16.4.2 AI). Now, the I/O section on each channel shows the inputs for each channel. QUESTION: What does each channel OUTPUT need to be? Output, or a BUS, or what to get it back to each individual channel? This is a Win 7 PC, 8gb RAM, Quad Core AMD, SSD HD. I do not have a problem recording and mixing off the computer but like I said, I want to bring each channel back through it's on channel in the 1642AI so that I can work with the FAT section and do mixing from it. Does this make any sense?
