Automatic Conversation Clearing - full clear context option and enable configurable settings in MW portal

While its very useful feature to ensure that auto conversation clearing helps to avoid impact from pervious (old) interactions, I would propose to also have the option to choose to perform full clear context (all the previous conversations) or keep the last interaction context (as current configuration).

These options should be made available via MW setup portal:

• Conversation Clearing: 
  • Full clear context
  • Keep last interaction context
• Lookback Period (in hours) of Conversation History (currently exists in MW setup portal)
