how to route an input PFI that I am using as a clock to an output PFI

Hi,

I have a USB 6218 and USB 6366.

I am externally triggering using PFI0 terminals in both i.e., signal from a function generator is input to PFI0 of 6218 and PFI0 of 6366

I am deriving 4 analog outputs, two from each for every clock trigger pulse. These are waveforms going from -10 to +10 V

However, I also want to output this clock when DAQ starts its operations to activate another external instrument.

Unfortunately, I am not sure how to do that.

adding triggered digital output port0/line2 does not work because on these devices clocked digital output isn't possible.

Is there a way that I can send the PFI0 input to PFIx output where x is anyone of 2 to 15?

I tried outputting the PFI10 to 'external' but got an error saying only one clock is allowed.

Or is there any other way besides using a third DAQ?

Thanks
