Single Sample Analog Output without using the analog input clock for a hardware timed loop?

I am trying to output single samples from a PXI-6733 at the time of the board's sample clock.  However it looks like the samples are output at the instant they are written using DaqMx Write Analog Wfrm NChan 1Samp.  It is not waiting for the time of the analog board's sample clock.

It looks like I would need to use a hardware timed loop, but for some reason, the loops can ONLY use the sample clock from an analog input channel.  My problem is that the analog input channels on my PXIe-6536 all need to run at a completely different sample rate (much faster) from the Analog output channels.

Is there any way to get single sample output to wait until the analog board sample clock or to get a timed loop to use a different clock (say from my 6682 or 6674 cards)?

Thanks
