Currently, there is the "Loop Geometry" entity where we can use a surface target if we want.
I would like a new entity : Loop Geometry (horizontal target):

Instead of using a surface target, I need to use a Horizontal target in my custom subassembly.
Moreover, why not a new element called:
SurfaceLink from Loop entities?
In this case, we type the "Loop Number", such as LO1, and we get a surface link from that loop.
I would like to be able to create shapes using some entity from a loop, but I can´t get the links from the loop.( I think that a surface link from a loop is a good way).
