Linear Pattern - Feature, Nest

Hello,

I am trying to place as many features (mold cavities, ~.25" is the max diameter of the cavity) into a 15" X 15" plate.  The seed cavity is composed of 6 extruded cuts.  I can easily populate the plate with cavities with the linear pattern repeat feature.  However, in order to populate the plate with the most number of cavities, I need to nest the cavities (see attached).

Currently, I am have to make two seed cavities.  Then, I perform two separate linear repeat functions.  Building the second seed cavity is time consuming, and subject to errors.  Is there a way to copy the first seed cavity to a specified location on the 15" X 15" plate?

Thanks
