I'm inclear how I'd mimic the settings of a multiparm block with an agent layer sop in APEX. I see the APEX sop def expects a dict-array. But when I try things like layername, or layername1 for the key values, it doesn't seem to register. Does anyone have a guage or working exmaple of setting a multiparm block with an APEX dict array? This seems to dive a little deeper in this case too because the bindings folder is a nested multiparm block.

The best way to see how the dictionary should be set up is to use the Import SOP Nodes button under General Scripts parameters on the APEX Edit Graph node. Use it to import an example Agent Layer SOP that you have. However there's some caveats here:
- There's a bug currently where for multi-parms, you need to make sure that they're NOT at defaults. So make sure you add a multi-parm instance when testing. And also change all the parms you want to affect.
- APEX currently doesn't support nested multi-parms. So in the case of the Agent Layer SOP, it means that we can't use it in APEX for shape bindings.
