Define a physical channel in MAX

I'm finding it difficult to locate the answer to what seems like a very easy question.

I have hardware differences between machines, but they all run the same LabVIEWapplication.exe

Hardware pins are defined in MAX as Task Names, as shown in the picture below.

I've started using the edge detection feature of the PCI-6515 card, but I cannot figure out how to define a physical channel in MAX for the edge detection input of DAQmx Timing.vi, shown below as Dev3/port0/line2. In MAX, task name "DI_InsideWin1" is defined as Dev3/port0/line2 but Task Names cannot be connected to the "falling edge physical channel" input of DAQmx Timing.vi.

How do I define that input in MAX such that I can deploy the same exe to all machines?
