If possible rename blame to codecov so I will use same command group for extension. I have one card which will provide codecov and cover commands like

1. automate and manual % as per assignee
2. automate and manual % as per FA etc...

Thanks for initialize this... I am facing problem with requirements but i will add basic implementation.
