I work in security and a use case I've had in the past and hacked together using a combination of Power BI and powerpoint (hey, license was already paid for!) was exporting tons of data from logs, load into Power BI to generate charts and metrics that related to security (especially vulnerability management). It was the same slide every time, just new data.

One thing that could be useful though is the ability to export a snapshot of what the slides would've been on any given day, for reference in the future (data might not be available in 2 years etc).
