This can be done by using only one caliper arm whether you have one or two. With practice this can be done quickly.
I just find it a pain to undo the wheel and reverse it. If I am going to get it out of the stand, I might as well use dishing tool which will give me a quite accurate idea of which way to adjust.
One thing that hasn't been mentioned is ensuring the bearings in the axle are in fact in good condition and properly adjusted. It's also a reason why I use the QR in the truing stand to tighten the bearings to their riding tension.
