Azurerm security center automation scope

In the terraform documentation it says

but if I add a 2nd subscription in this array, I am getting the error message

Error: creating Automation: (Name "defender_automation" / Resource Group "rg-blablabla"): security.AutomationsClient#CreateOrUpdate: Failure responding to request: StatusCode=400 -- Original Error: autorest/azure: Service returned an error. Status=400 Code="BadRequest" Message="Input Validation error: Scope at index 1 with description scope for /subscriptions/9274a..... must have the same subscription ID! (Configuration's subscription ID is 31d40211.... while scope subscription ID is 9274a765....., error tracking number: 0301a337....."

Does that mean that if I need a 2nd subscription to be monitored I have to add another instance of azurerm_security_center_automation ??

If the answer is yes, the documentation is wrong or at least misleading

No answer available for this?
