Analog output with analog start trigger: invalid trigger source

Hi, I got Error -200265 (invaide trigger source) when trying to use start analog output with analog start trigger. The returned error information says

 

Property: Start.AnlgEdge.Src
Corresponding Value: PXI1Slot2/ai0
Valid Choices: APFI0, APFI1

 

I am very surprised why it is not possible to use one analog input channel to trigger analog output, which on the other hand, is possible for start analog input. I searched online and found a clue: someone sayed that "Unfortunately, PFI0 is the only terminal that can be programmed as a analog trigger source for an AO task." http://forums.ni.com/t5/LabVIEW/DAQmx-trigger-AO-from-AI-signal-error-200265/td-p/1197743

 

As the above question was posted 5 years ago, I am wondering whether it is possible now? In my opinion this is such an important function, NI should have made it possible. By the way, my daq device is PXIe 6358, which has 16 AI and 4 AO, 1 APFI.

 

Happy New Year!

Have you tried what that other thread suggested and wired the analog input to both?
