attaching tracker to mask

Hi folks,
I'm having a problem attaching a tracker to a bspline mask - apparently there used to be a script called "Attach Mask - XF - Stroke to path" to do this. However this is not available in Fusion 8 (on Mac). Can anyone point me in the direction of a work around or give me a hint on how to do this?
Many thanks in advance
