Setting relative paths

I remember being asked when updating models if I want to make media paths relative to the model file/directory. Is there a way of forcing the model to make it's current paths relative rather than expicit?

Save your model, then run this script:

treenode updatemediascript = node("MAIN:/1/exec/globals/nodefunctions/updatescripts/UpdateMediaPaths");
nodefunction(updatemediascript,model(),4.0);
