  We study the effect of inter-condensate dipole-dipole interactions in a setup
consisting of physically disconnected single-species dipolar Bose-Einstein
condensates. In particular, making use of the long-range and anisotropic nature
of dipole-dipole interactions, we show that the density of a {\em target}
dipolar Bose-Einstein condensate can be axially confined and engineered using a
trapped {\em control} dipolar condensate. Increasing the number of control
condensates leads to exotic ground state structures, including periodic
patterns. The latter consists of single and double-peaked structures with
coherence between the peaks controlled via the separation between the control
condensates, thereby accessing both supersolid-like structures and incoherent
arrays of density peaks.
