Execute script against particular database in PostgreSQL

After 2017.2 update there is an option to combine all PG databases on the cluster to one datasource.

When I create .sql file and want to deploy on the server on some particular database I hit Ctrl+Shift+F10 and choose datasource. I have no ability to choose any database and this script is run against default database (postgres in my case).

If I try to attach to console, there is no visibility what database it uses during this moment. Is it any option to choose database as well as datasource during this execution?
