Adding tables to ER using templates

I have an update anywhere ER solution already established using templates. I need to add some tables to the database and to ER and I want them to be a part of the same replicate set as the template created. I would also like for the tables to be a part of the template that was used to define the ER solution in the first place. I'm at a loss as to how to occomplish this. Does anyone have any suggestions that do not include deleting or stopping any of the existing replicates? Thanks, DL Redden
