Databases in Jetbrains Rider

Hi,

I got a microservice architectured application here, each microservice got it's own database, but on the same domain.

Is it possible to add all databases in Rider and execute queries across those databases? The database engine is MS SQL.

When adding the databases one by one, then I'm not allowed to query across those databases. When adding a single database, I can see the schemes of the other databases but can't actually do anything with the databases directly.

Thanks in advance.
