Notify users with a pop up message

Hi Power BI community,

I have many dashboards currently contain data quality issues coming from a few business divisions that are likely to take months for the divisions to fix, and I wish to keep these dashboards as they are, but to notify dashboard users to be cautious of how they may interpret the data coming from those problematic business divisions. 

Is it currently possible to configure within Power BI Service, so that when users click onto a dashboard/dashboard page, they see a pop up message informing them about this ongoing issue, and for Power BI Service Admin to easily remove it once the issues have been resolved?

Thank you!
