Sorry, I don't follow what you mean with bare wire to ground. The circular rings are both ground for each channel. Once you link the two grounds as you have done, all the outer ring holes are ground.
Thus, you can use any of the holes in either of the outer rings for your ground connections. Again, I am not sure what is meant with the bare wire idea, but you should have plenty of holes to choose from, thus I would use those.
Edit: I guess I see the problem you are running into. There are several solder joints on your outer rings that have 3 of them very close together. If you look at your photo, you will see it on the left and right rings in the same line as your ground wire. Those middle solder joints should have been open, but it looks like VALabs made a mistake there. If you look at my picture you should immediately see the difference. Each ground wire is in its own hole.
I am guessing that you are running out of physical holes to place your ground wires in. You can either try and remove the solder on those joints, but when I was working on it, my temperatures had no impact on those joints at all. Another option would be to see if there are any open ground holes close to the top plates. If you have any there, see if you can get a ground in there.
I can now see why you are considering a hook-up wire, however I do not like the idea of having too many loose wires. It should work, but you would need to ensure that it is properly attached. I would prefer attaching it at 2 points. One potential way might be to remove the sleeving of the wire you used to connect the 2 grounds (the short black one) and use that for all of your ground connections.
