Enable Callable Agents outside of webhook send/receive functionality

I love the functionality that you have enabled with callable agents and the webhook (future flow step) application.  What I would like to see as a next step is the ability for agents to execute other functions in Marketo beyond sending back return attributes to populate fields.  Here are some recommendations for capabilities to add to callable agents:

• Add to List
• Insert/Upsert on lead database fields across objects (Program Member, Marketo Custom Object) 
• Change Program Status
• Add/Update to Salesforce Campaign.
• Conditional logic for change data value (rather than merely send back responses)
