Is there a way to call the same note in the Memos app using this.controller.serviceRequest?

right now i'm doing this:
Code:
this.controller.serviceRequest('palm://com.palm.applicationManager',{
  method: 'launch',
parameters: {
   id: 'com.palm.app.notes',
   params:{
     text:artist+ ": " + track //  passed  when this function is called
    }
   },
   OnFailure: onFailure,
   OnSuccess: onSuccess
});
this works great but it always makes a new memos entry when it's called. I just want it to append to the bottom of a single memo.

Anyone figured out how to do this?

I'm hoping it's one of the params to lookup a specific note or something.

Does anyone know where i can get a list of all the parameters from each of the applications in com.palm.app?
