Can dolphin know where it's located?

[Aylamao]

Simply put, I want a more Portable Experience™ by, say, having dolphin in a plug and play external hard drive. I don't want to reconfigure dolphin everytime I plug it into somewhere new, so is there a way to specify, particularly in the config, a type of string that will let it know to look in it's current folder in the current drive?
