Routing start trigger to RTSI/PFI (NI-6110)

Question

We've got a customer who is trying to route a start trigger to a PFI or RTSI line.  He is not using LabVIEW as can be seen below and is using traditional NI-DAQ.  Can you please confirm if it is possible to do using the NI-6110 and traditional NI-DAQ.  I've included his email as well which contains the relevant information.
"As explained I use 2 Ni6110 cards at Wits. These cards are synchronized via a rtsi cable and operate in pre-trigger mode based on an analogue trigger on channel 1 of the master card.
Everything works well, but I need to be notified via a digital line (or RTSI line) when the trigger condition is met. At present because of the stop trigger method of configuring the card, I get notifed when the stop trigger condition occurs. This is obviously too late in the process.
The following relevant commands are used:
DAQ_StopTrigger_Config(NiDev1,1,PostTriggerPoints*NoofChannels);
Configure_HW_Analog_Trigger(NiDev1,ND_ON,LowValue,HighValue,TrigMode,TriggerChannel-1);
Select_Signal(NiDev1,ND_IN_STOP_TRIGGER,ND_PFI_0,ND_LOW_TO_HIGH);
//The following line is used to get the second card to be synchronized with the first card
Select_Signal(NiDev1,ND_RTSI_1,ND_IN_STOP_TRIGGER,ND_LOW_TO_HIGH);
On the second card:
DAQ_StopTrigger_Config(NiDev2,1,PostTriggerPoints*NoofChannels);
Select_Signal(NiDev2,ND_IN_STOP_TRIGGER,ND_RTSI_1,ND_LOW_TO_HIGH);
How can I be notifed of the start trigger condition?
I thought that something like the following could work, but I have not verified it. I need the signal to be available on a 6224 M Card:
Select_Signal(NiDev1,ND_RTSI_1,ND_IN_START_TRIGGER,ND_LOW_TO_HIGH);"
Thanks for your help.

I looked at the Device Routes and the Device Pinouts in MAX and
found that you are not able to route any of the digital lines on port 0
to the RTSI lines, only those that are directly linked to the PFI
lines. The counter lines are all directly routed to the PFI lines. In
the Device Pinouts chart it shows that the digital lines on ports 1 and
2 are directly routed to the PFI lines. Please refer to that chart and
then you can use the DAQmx Connect Terminal VI for simple easy signal routing.
To see the Device Routes in MAX: Select your device and then select the tab at the bottom titled Device Routes. Green means you can use the DAQmx Connect Terminal VI. To see the Device Pinouts in MAX: Select your device and then press the button at the top labled Device Pinouts. You can also right click on your device and it is listed there.
