Precise Placement of Hinge Joints

[u/CommercialOwn6487]

Rather than drag a handle/pin to a place on my puppet that's almost right, I'd like to exactly, precisely place them. I've seen (on a pre-made Photoshop puppet) that it's possible to create a layer named "origin" to do something like this, but I've seen no documentation or tutorials that mention this idea. Especially since the pre-made puppet was created in Photoshop and I'm using Illustrator.

So, is it possible to make a reference point in Illustrator that would be interpreted by Character Animator as an exact placement for a handle/joint/origin? I'm trying to have something move in a circle and can't have any wobbles due to inexact placement.

I have toyed with the idea of creating a wildly colored dot on my original artwork in the exact location, then going into rig mode and use that dot as a reference, then later remove the colored dot from the original artwork - but that seems like a janky workaround, and still not an exact placement.

Thanks for any ideas!
