RTCz V3 - passing parms in TRANSLATOR - using TSO command/ex

I created a translator that executes a TSO exec and I put some parms on the comand line to pass to the exec. Here is the command

EXEC 'POULIND.RTXZV3M7.ZEXEC(TREX)' 'DB2Y,grp,ptype,dbrmname,plan,"${teamz.scm.dataset.prefix}.BINDSTM",BXB076'

I am able to pass the fully qualified name of a dataset usng the ${teamz.scm.dataset.prefix} variable.

Now the question - I need to pass the member name of the member bing "worked" on during this execution and am not able to find how to do that - any ideas?
