Preventing AliasExistsException

I configured a Cognito User Pool with "Option 1: Multiple sign-in attributes (alias attributes)". I configured phone_number and email as alias attributes. The document says "Only the last user who has verified the attribute can sign in with it". I first confirm account and verify email attribute with ConfirmSignUp API. Then I user VerifyUserAttribute API to verify phone number. ConfirmSignup API has ForceAliasCreation parameter so that I can override an existing alias. However VerifyUserAttribute doesn't have ForceAliasCreation parameter. This creates two problems:

• After sign up and confirmation, I can't verify Phone Number if there is an existing alias
• After UptateUserAttributes I can't verify Phone Number or E-Mail Address if there is an existing alias

How can I prevent AliasExistsException and force alias creation in these scenarios?

Best Regards
