Release cable ajustment

My 2003 Eclipse has a hatch back release cable with a lever beside the driver seat. There is one adjustment in length built into the cable.I have used that adjustment and the cable is still too stretched to fully release the catch. Does anyone know of an easy way to shorten this cable. I realy don’t want to replace it as it runs under many things on the way to the back of the car. 4flashman@comcast.net
