probing all top mdules to a particular depth using $shm_probe

Hi,

 I have a testbench in which each test case adifferent assertion module. The assetion module is a top level in heirarchy(parellel to my test bench top which instantiates DUT). I need to dump the waveform for these assertion modules using shm_dump.Is there any way to do it without editing the shm_probe after each test case run.

I tried $shm_probe( $root,AC); , $shm_probe(*,AC).... but that gives compilation/elab errors

Thanx in advance
