* automated emailing of reports:
I've already implemented a way (not yet released) to email End Session reports at any time, as they are configured on the End Session tab. I did this for you, but I after re-reading your post I don't know if it will work for your needs.
You will notice that already, UNLIKE the interface for email you are doing now, the interface on the End Session tab DOES save and LOAD the last template you used on it, just click the "Save Settings" button to save the default email config and template too for the End Session tab.
Now, I think this should solve your issue. End Session tab automatically loads your default template, and the automated function emails it wherever you choose to use the automated function.
What occurred to me after re-reading your post is that you might be using the checkbox to "Make Body: Info Report" or "Work Report" so that the body of the email is the report you are looking for. If you use this method, then you would need to change the button on End Session to "Info Report" when you start work and "Work Report" during End Session.
Is that what you are doing? Or do you care at all what is in the body of the email, so long as you have the attached reports?
