I have Version 7 but it does not really do the trick either.
Live-Copies might work in some limited Scenarios but would require previous manual tiling.
Live-Copies also do not store Transforms - so if you move, scale or rotate the Input all Live-Copies just stay in place...
What I was thinking of was Functionality found in Pattern Studio, such as visible here I'm pretty sure that was very easy to add.

Basically it was an automatic patterning of Input Geometry by their Bounding Box while leaving all components editable.
Here one sees the entire pattern but you certainly could imagine the pattern clipped to the Boundaries of a Fill-Objects.
