cheers
Yes, you can do this, that's one of the reasons I put them there. Im taking 4mA from the +5V supply for my CCS. If you use the -5V just be aware that i've labeled it backwards, GND and -5V should be swapped around. Also note that the more current you take from these supplies the more you are effectively increasing the output impedance, but a few mA shouldn't hurt it much.

Thanks. Very convenient.
