Psscale: control the size and label position of NaN rectangle?

Using GMT 6.4.0.

Is there any way to adjust/control the size of the NaN rectangle plotted using gmt psscale -D+n? Likewise, can I control the label placement? Ideally, I’d make the box a little smaller, and closer to the rest of the color bar. Also, the default behavior seems to place the label to the left of the box, but for my application it would be desirable to plot the label below.

Many thanks,
