Hi brad,
Yes, with a MoGraph Selection.

(If you use MoGraph Weight, you can determine the influence amount.)
Set up your Voronoi Fracture scene, then call up the Main Menu> MoGraph> Tools> MoGraph Selection, and “paint” over the clones to select those.
This will establish a MoGraph Selection Tag, which can also be set to be used with Fields.
An alternative place to find and add a MoGraph Selection Tag is given in the Object Manager> Tags> MoGraph.
Please let me know if you have any questions. I’m happy to look into it.
All the best
