Yes! You can either create a new data source per account or you can edit your existing data source to add more accounts.
(If you meant to find how to log into multiple user accounts - please see Can I Add Multiple User Accounts to the Same Data Source?)
Adding a New Data Source
- In your report, click Resource->Manage added data sources in the top menu.
- Click ADD A DATA SOURCE.
- Under Partner Connectors (or in the search bar), look for the data source you want to add another account for. Hover over it and click SELECT.
- If necessary, authorize access to Data Studio and then log into the data source.
- Go down to the option to select accounts/pages/profiles, based on which connector it is, and select the additional account(s) you want to use in the report.
- Give the data source a new meaningful name so its easy to tell it from the other sources for the same platform.
- Click CONNECT to save the new data source, and then ADD TO REPORT to include it in the source options for your report.
- You can now add the new source to any report elements in the report!
Updating an Existing Data Source
- In your report, click Resource->Manage added data sources in the top menu.
- Find the data source you wish to add more accounts to in the list and click EDIT.
- Click EDIT CONNECTION from the field list to go back to the initial configuration screen.
- If necessary, authorize access to Data Studio and then log into the data source.
- Go down to the option to select accounts/pages/profiles, based on which connector it is, and select the additional account(s) you want to use in the data source.
- Click RECONNECT to save the change to the data source, and then APPLY to confirm any configuration changes.
- Click DONE to go back to the report. Now any report elements that use that data source will include the other accounts selected!
WARNING - If you update an existing data source to add more accounts, ALL reports and report elements that reference the data source file will also update to include those accounts. If you do not want this, make sure to use the first option to create separate data source for each account.
