Reporting on user status history

Is there anyway to report on a user's status history (Active, Mobile, vs inactive)?

I have a manager that's trying to review some data related to her employees who are currently WFH, and how much time they are active on their workstations.    Since Skype for Business shows their current status, I thought it had to be logged somewhere.  

I've searched through the reporting and logs, message boards, etc, and can't seem to find anything other than user activity related to Chat, email, calls, etc.

Thanks,
Rob
