Is there a way to create repeating random stepped voltages just like the voltage block?

Sure...one of the easiest, in fact, would be to use an LFO to feed a clocked quantizer. Adjust the LFO rate accordingly, and you'll get the basic pattern...but you can also OFFset that rate so that the resulting patterns become longer. And the waveform chosen will also affect how this works; ramp waves (ie: reversed sawtooth) will give you an "up" direction, sawtooth will give you "down", and the other cyclical waveforms will do the same over up and down.
