How to edit object deformed by a curve modifier In the objects that are deforming along a curve, I would like to know how to move an edge along the curve.

When I try to edit an object that is deformed along a curve in the "Edit Mode", the object reverts to its original form. I want to edit in a state of being deformed, before applying the modifier.
And if possible, I want to move some edges along the curve that are used for deformation. Sorry for my poor English.
In the modifier there are two options that will allow you to work in edit mode. 



The first one will allow you to display the modifier in edit mode.

The second will allow you to edit the mesh while is being deformed by the modifier:
