[modeller_usage] Missing Residue Modeling for an Oligomer Inquiry

Hello, I missing residue modeled a loop region of a monomer from an oligomer heptamer and then oligomerized this new model monomer via GalaxyWeb into a heptamer, however, the generated heptamer´s RMSD to the PDB structure is a great 40 A.

My understanding is that my above methodology is how Modeller would function best due to interfacing of multiple subunit problems if I tried to missing residue model all seven loops with missing residues. Is it possible to try and missing residue model the complete heptamer regardless due to my generated heptame exhibiting an unsatisfactory RMSD Value?

Thanks
