Option enable/disable creation of subfolders for download attachments

Currently when you set-up automation in FME Server, the trigger option include email received. One of the option for email received is download attachments. You can specify a location to save the attachment. This can be on FME server or network location where FME server account can write to. However there is a new folder created each time the automation is trigger and this can be annoying. It would be great there is an option to enable/disable creation of subfolder and also possibly save the attachment and overwrite the existing file.
