I have created and named several new templates using "Settings" -> "Printout Report Template" -> "New from the current report".
Now, I would like to change names of these templates, but not the name of the whole printout report created.
To rename a template, go to the printout report, and select on the menu "Settings"-> "Printout Report Template" -> "Select." By clicking [Rename selected printout report template], you can give the template a new name.
To rename of the printout report based on the template, select on the menu "File" -> "Rename" and specify a new name.
