[FV Transformation] Redesign names transformation
If the Named elements are not added to the map then each time the transformation is executed the name is changed (which is undesired).
Moreover, I do not see the point of adding the names in the map. IMO the transformation should work fine even if we are not saving the names in the map.
I had to add the elements in the map to preserve the "functional" nature.
Rethink about it and try to find out if there is a better approach
