Welcome to eazyBI community! Thank you for raising this point. Currently there is no such feature, but we have discussed it before (you can read about it here - It would be good to have a inbuilt version control / Report changes history with EazyBI repors 5) as well as added it to ideas in the eazyBI backlog.
I added your vote to the improvement and will update this community post once there is any news regarding it.

Visit the documentation for more details: Audit log.
Here is a short video explaining and covering the main functionality:
