VSCode Connections Local and Remote - Best practices?

Hi noble developers!

Have a question/discussion. Sometimes, while developing, we'd need to connect VSCode directly to a remote server (e.g., stage one) for debugging purposes. And after change back to local one. And then to remote again.

How do you perform this switching in VSCode in a convenient way?

I have several settings.json files (settings_local, settings_remote) which I put to a main settings.json when I need to make VSCode to connect to switch the connection:

Is it the best practice? Or maybe there is some option to make VSCode remember several of them and easily switching via command/button and indiicate clearly where I am? 

I develop locally for both cases.
