Modeller should do this automatically, since the template information is weighted by the local sequence similarity. Of course, if you want to bias the construction more, you can always deliberately misalign the other templates in that region, so that you use only the one template (although all templates would be used for the rest of the protein). An alternative is to manually extract some key distances from the 'best' template, and use these to add your own restraints to the modeling procedure.
