Yes, pretty much so.
The difference is that the PSU needs to be set to a higher voltage, to allow for the lamp or resistor voltage.
Something like a car headlamp bulb should work, they are very low resistance when cold and if you have an ammeter in series you should be able to adjust the PSU output to get around C/20 rate, eg. a current 1/20th of the amp-hour rating or around one and a half amps for each single string of 32AH cells.
You could do two or three strings at the same time, but use a separate lamp in series with each - do not directly connect sets of cells in parallel, as if there is even a slight difference in voltage the current could be enormous.
Once all cells are fully charged and have been on the low current trickle for a day or two as above, if you wish to parallel batteries you can connect the negatives and use the headlamp bulbs to cross-connect the positives until the all the battery voltages are exactly equal, then direct-connect them.
