If you have the older style Quicklinker definition file, then you can use link:<connnector type> in place of the object type to describe the origin and/or destination.
For example, this allows the creation of a derivation link between an Association and a Composition:
link:Association,,link:Composition,,,,,Abstraction,Derivation,to,derives from,derives from,True,,,True,Derivation,0,,,,,
