Automatic timeline marks based on application output

Dear VTune developers,

This is a suggestion of a simple feature that I would find very useful in VTune.

Introduce an option to automatically set timeline marks based on application output.

For example, for each text line sent to stdout, or for each line starting with a given tag; allow user to see the application messages along with timeline marks. This would much save the profiling effort for a long running process. I know I can mark timelines interactively, but this is not very accurate and requires one to constantly watch the application activity. I also want to avoid using ITT API in my application.

Thanks,
Kostas
