Sure it's easy enough to amend the 'Default Maps & Data Path' but can you change the default QuickProject folder naming convention from "QuickProject YYYY-MM-DD HHNNSS" to something else?
As suggestion may be to use the name of the template selected when running the QuickProject wizard instead (eg: "Fire Perimeter YYYY-MM-DD HHNNSS") or allow the user to select the location (similar to the GPS Tracklog Filename properties)
