[sdiy] ground & power on pad-per-hole solder breadboard

Thanks for all the replies...
I was just looking at the PCB for the MOTM-420 which I've received but not
assembled yet...it has the +15V supply connected to an op amp, and the +15V
trace continues to an LM13600 and then another op amp, etc ...that's what I
meant when I said I planned to daisy-chain my power pins on my board. My vco
plan has 3 TL07x op amps, a 4016B, and a CEM vco chip (ok, so I cheated!), so
total current draw is not too much, and perhaps I can also use this way of
supplying power. Of course, it wouldn't be too much more trouble to run wires
from each IC's power pin directly to one spot on the PCB either.
And for ground, I was going to wire down the between the rows of ICs and
passive components and solder them to the wire to make my ground connections,
like this (hideous attempt at ascii picture follows):
-------------------------------------------------

---------- cap --------------- |
| 4016B | \---| CEM | |
---------- --------------- |

---------- res --------------- |

I'm mostly copying what I did on the solderless breadboard. So, I suppose that
if the CEM is doing something to affect the ground, it'll affect the 4016B
which is "downstream" on the ground connection, yes?
