Accurate alignments possible?

I'm trying to rough out my 3D printer design in MoI, and still frustrated by my inability to precisely move items to where I want them.

For instance, my first part was creating the profile of the extruded aluminum I'm using. Because the center is hollow, I can't move it by the center (from it's end profile), instead I have to grab a filleted edge which causes it's own issues trying to snap it to another object.

I still would like a way to select an object, and move it precisely by entering coordinates, either by it's volumetric center or select a point on the object and have the ability to type in coordinates where the object should relocate based on the selected point.

Maybe I'm expecting more CAD functionality that what MoI was intended for.
