Sorry DaleB, but a morphed tounge can do everything an articulated can. At least for the normal range of motions a human can do.
The problem you have is just that the default DAZ tounge morphs aren't very good.
You can easily control V3's tounge origin right in Poser.
Make the tounge a new group, add a magnet, let the magnet zone influence the tongue group only, and you can easily lift, scale, move, do whatever you want with the tounge.
Then save what you need as morphs.

Same with toes. The existing toe morphs are just not good, and 20 additional bodyparts give Poser a LOT more stuff to calculate while rendering.

Yes, you can theoretically "bone" anything and then double- joint every joint on top of that to get smoother transitions but then posing and scaling and morphing and cloth creation becomes very, very hard.

If you need a fully articulated  "super tounge" for a fetish or fantasy render, why not make a conforming tounge figure?
Something you can add to V4 when you need it, but that won't use your system's RAM or get in the way of morphing when you don't need it ?
You think V4.1's tounge is the bees knees ?
Regroup it into 20 or 30 sections, then add easypose controls.
THEN you'd have something special.

But make it an add-on and don't pollute the main cr2 with extra bones and bodyparts.
Keep the main cr2 as simple and rugged as possible.

Same with articulated toes. Easy to make a second set of toes that can be added with Poser's built in geometry switching. Then add the additional joints with a joint pose and you can let Vicky flip-flop along the beach to your hearts content.
But leave the default figure as simple as possible, because most of the time fully articulated toes are just not needed and just drain your system resources.

That would be SMART TECH.

DAZ threw every gadget they could think of at V4 and hoped it would stick.
And then they were surprised that she constantly crashes and burns at the slightest instance.
