MySql - How to filter data into Power BI

We have a MySql database on an Amazon Cloud server and there are multiple customers accessing it and, of course, each customer gets to see only its data.

I want to create a number of dashboards / reports which will be common to a group of customers in the same industry.  Obviously it is imperative that a customer does not get to see competitors information.

In the MySql database each user signing on is immediately identified as belonging to a particular customer.

Is to possible to pre filter customer data ging in to Power BI?
