[boost] Boost Graph Library Property Map

Is it possible to convert other Property Maps to Vector Property Map? My requirement is that the property map should be able to grow/expand (as I am using it with a dynamic graph which also grows). But I want to make it generic so that it works for any kind of property map. So I think if I am able to convert any type of property map to vector property map then I can grow the property map, when I add new vertices to the graph. Thanks, Manas.
