Multipe syncgateway databases for same bucket

Hi ,
I am trying to push the data from multiple devices into sync-gateway through multiple databases , but to same Bucket .
How can i design my config file with multiple databases pointing to one bucket.
(please send me some sample file )
thanks a lot

This configuration is not supported, each database must have a separate backing bucket.

What is the desired use case for using different databases on SG that all map to one bucket?

We use the logic in our code and call the appropriate syncgate rest API (by appending the db name at the end url)

now we have four diffrent databases like comments , sales,db, h_db.
