Using the map pins function without a listing

Does anyone have a suggestion of how to add a pin to GD maps without having an associated listing? It would be useful to map service points like cashpoints, banks, parking, taxi ranks etc without necessarily having a listing attached. All I really want is the pin on the map.
I am guessing this is probably best done by creating a personal map at the maps level and then utilising it as a bespoke Google map but does GD allow this and if so has anyone ever done it?
