Non integer # of samples filter delay - PXI 4461

Is there a way to get the digital filter delay to an integer number of samples? I went through the DAQmx help (in the timing, trigger, device and channel properties) for the PXI 4461 looking for a hardware way to compensate the fractional sample delay but cant see anything.

 

An obvious one is to disable the anti-alias (63 samples fixed delay for the AI I believe) but I need it. A second one is to implement a fractional phase shift in the acquired data later in software but I dont quite like this.

 

This delay I need to be integer for both the AO and the AI.

 

Thanks,

Aleksandar
