Cloudwatch Logs Streams Organization

I have a question about organizing Cloudwatch Logs streams when using the CW Logs Agent. When setting up the config file, there are certain variables that can be used (instanceid, ipaddress) that can cause logs to drop into different streams. My customer would like to configure the agent to monitor a specific root directory, and create separate streams for each specific log file that lands in that tree. Is it possible to configure the agent in this way?
