You can do exactly that withe the noose(s) included in https://zonegfx.com/davos-terminus-4-total-carnage-package/, BUT, you will have to adjust it yourself, then save it as a wearable preset (you probably want to save the pose or part of the pose at the same time).
A tip: depending on what you want to do, sometimes you need two nooses, one part is around the neck and the other is hanging down in front or behind or whatever. Just "glue" them together so it looks OK and hide all the parts of the nooses that shouldn't be visible.
With Davo's noose you can do pretty much whatever you want.
NOTE! Davos noose is NOT for G9 (its for V4 and M4) but that doesn't matter as you have to do all the adjustments yourself and then parent it to lower neck of G8 or G9..
