When working for a lot of customers, it is a good idea to keep their data stored in separate databases. The software running on it will access its own tables, but requires updating of the roles of every new customer. The only solution currently would be to use the Atlas admin api, to automate this.

A much more elegant way would be if we could use a wildcard in the resource specification. For instance: `resource: {db: "customer_*", collection: "products"}, action: ["find"]`.
