DAQ toolbox digital output pulse

I'm using an NI DAQ PCIe-6321 and the DAQ toolbox and I want to know if there is a way to output a pulse on one of the digital output lines with a precise duration, for example a 10ms pulse. I can't see anything in the documentation about this. I can output a 0 and then use a pause command or similar and then output a 1 but this is very imprecise. I am aware that I can use the analogue output to do this but I've run out of analogue outputs and similarly I'm aware that it can be done with a counter channel and 'PulseGeneration' but again all of the counter's are in use.

Any suggestions much appreciated!
