Transforming a model using 2D views

Is it possible to show (and manipulate) the transform white cube in the 2D views? I would like to move my part within the plane of the 2D view. My application is placing an orthopaedic implant in a ct data set.
Thank you in advance for your help.

We plan to add transform widget to slice views at some point, but since there are more direct and more accurate (semi)automatic registration methods, adding a fully manual adjustment option has not been a priority.

You can adjust transforms in slice views by moving markup fiducial points if you use Fiducial registration wizard module (in SlicerIGT extension).

You can write a short Python script that adjust transforms based on markup fiducial point positions (see examples in script repository).
