Google Spreadsheet Data Sources with custom client_id and client_secret

When getting an OAuth Refresh Token, it needs to use a fixed client_id and client_secret such as
"217138521084.apps.googleusercontent.com" and "gXQ6-lOkEjE1lVcz7giB4Poy".

Currently, no way to change another client_id/client_secret.
It had better to be able to use the client_id/client_secret from each google account.
