Grafting using antibody.mpi.linuxgccrelease and specifying custom template which doesnt have pdb id.

Hello all,
Using this command to graft from a specific template
antibody.mpi.linuxgccrelease -antibody:blastp /home/rosetta/ncbi-blast-2.13.0+/bin/blastp -fasta antibody.fasta -antibody:h1_template  pdb_id

Can we use the same approach for grafting where we dont have a pdb id to specify template and use a specific structure instead ??
