How to do multiple database connections without using coded step?

Hi,
I have few queries around how to do database connection in Telerik Test Studio. I am able to do it from Coded Step, however needed to confirm if it is without using Coded Step.

i) I am able to connect to a database and get the data from single database. Just need to confirm how to retrieve the data from two different databases.
ii) I want to create a config driven script where environment (Stage, Sandbox, QA etc.) is read from the config file. Each environment having different database connection string, so here I want to read the database connection string from config and pass this connection string to create new data source. Is it possible without using coded step?

Thanks,
Kanif
