Hi Mindset,

re:

You can do this currently with the Transform > Move command.

Select the object you want to reposition, then run the Transform > Move command. At the first prompt to pick the base point, pick the point on the object that you want to position numerically. You can click the "Bounding box center" button if you want to position that spot of the object.

Then on the last prompt to pick the target point you can type in the x,y,z coordinates for where you want it to go.
