You almost sort’a can do this, but it’s tricky and probably wouldn’t give a very good result,. You would be better off just breaking out the lips into two separate elements with their own deformation. However, in a pinch when dealing with less than ideal elements provided from a design, I’ve used multiple chains on a single piece of artwork…and got mixed yet for the job satisfactory results.
You can build two chains, and then pull them into the same group and then use a Deformation Composite to bring the two chains together. The Deform Comp is more or less legacy and was once used for multi-chain builds, but you can still use it here to achieve what you are looking for.
Again, I wouldn’t really recommend this, but there you have it!
