Controlling How Run Messages are Logged for a SubModel

When using SubModels, you can control whether or not Run Log messages related to the SubModel are written to the parent model's Run Log.

This can be controlled from within the SubModel dialog:

By default, Logging of SubModel Run Messages is set to "Include". Optionally, however, you can set this to "Ignore".

When SubModel messages are sent to the Run Log, it is clearly indicated which model or SubModel generates the message.
