It may be that even these subVIs might not do quite the trick depending on what you want. If you want to get exactly the same random number (or array) from the Gaussian White Noise.vi for example, you may need to edit the VI and create a personalized copy.
In the existing VI, the seed value that you input as a parameter is actually 'randomized' on the first run of the program (open the VI and look at the case statement inside the loop). If you want the same seed to always kick off the same set of random numbers (for re-testing at a later time) you'll definitely want to take that code out. It is as easy as moving the two cluster constants outside the while loop (as initial values of the shift registers) and deleting the rest of the case (and re-attaching the broken wires), so it's not too bad at all.
