Basically an Array Modifier from Blender.
Justification
Scattering nodes in IMT do not provide this simple utility of creating a line of points upon which an input gets instanced without laboured masking or offsetting the scale deformations everytime one changes the distance between the input. This would speed up creation of, for example, hard surface details or instancing of regularly spaced artificial object much quicker.
Implementation Details
Well, I have made a very crude implementation myself.
I just create an offset for each object thus creating a line of them in a certain direction. Then I scale the whole image back proportionally. I am sure anyone could do better. 
Thank you for considering this!
