It's very convenient in various character scenarios to be able to manipulate the geometry points at the object level. While generaly is OK to make a handle permanent, sometimes you need to have the transformations placed in a hierarchy. The obvious example is a character deformed with a lattice, when you need to transform the points of the lattice and maybe to place them in different hierarchies, at the object level.
This is doable right now, with CHOPs or expressions or obj merge SOPs, but requires some work.
I think it would be nice to have the option of “glueing” a handle to a null.
So, in my edit SOP for one point of the lattice I would rt-click on the handle and choose: create null for transform. A null would be created at the same level with the object holding the lattice, and the handle will get the transformation from the null. You can then transform and parent the null and the handle (and its associated point) will stick to it.
