Databag to manage environment specific secrets

We are using Policyfiles and not using roles and environments.
How Can I have a databag to hold the secrets which differ across environments. For example,
For Dev, database is devdb and user is devuser and passwd is devpass
For Prod, database is proddb and user is produser and passwd is prodpass
I want the above secrets with different values yet to be managed by same data-bag or vault? Is it possible when I am not using environments or I have to maintain them separately.
