Detach Cable Actor In Matinee Or Sequence

Iv been animating a sequence for a level that contains a object connected from one mesh to another via a cable actor.

At some point in the sequence, i want one end of the cable actor to detach from one of the meshes, however after several hours of testing i have not been able to find a easy way.

I know Matinee and Level sequence let you add bool property and other tracks for editing parameters in a sequence. I was wondering if anyone knows of a way of changing the attach end to parameter or would it be easier of just destroying a actor the rope is attached to?

And help is much appreciated.
