The Create Template feature has a "Template Options" dialog that allows you to apply affixes to a component when dropping it into a template (e.g. automatically appending "_L" and "_R" to the end of point and component names). This feature doesn't extend to the points' parametric constraints. Currently, after dropping a component into a template, the program adds "-" to the left-hand parametric constraints if there are duplicate constraint names on the left and right sides of the template, requiring the user to seek out all of the parametric constraints and rename them manually.
