Hi Blake,
You can change the name of a report by clicking on the … beside the “Choose Template” dropdown in the “Send an Email” section when you create a new activity. In the “New/Edit Email Template” screen that comes up, you can select the template on the grid on the left which will then populate the “Name” field for the template. Once you change the name, it will replace the old name on the grid and update it with the new name.
On another note, when you generate a PDF to use as an attachment, it takes the report name that was created for it and then appends the date that it was sent on to it. We don’t have a feature that will allow us to change the name of the file that is generated.
I hope that helps.
Ronen
