Is there a function to remove the appendAnchor's points .

[Coder-345]

I appended my cloth to the arm by using

SoftBody.appendAnchor( 0, arm.userData.physicsBody, false, influence );
SoftBody.appendAnchor( clothNumSegmentsZ, arm.userData.physicsBody, false, influence );

But I also need to switch between anchoring the cloth and removing the cloth from the arm just like the one in this example : https://threejs.org/examples/webgl_animation_cloth.html
Here there is an option to toggle pins.

Is there any function to remove the anchor points
something like removeAnchor() ;

I am wondering it too.
