Advanced Options with RequestAuthAWSV4Signer

Hello,

I am using the OOB method for a credential Algorithm using Amazon Signature Version 4 with RequestAuthAWSV4Signer script include. Everything seems to be fine, but my API requires AWS Region and Service Name to be populated with the request. In Postman I can get this work with no issues, but in ServiceNow I do not see an option for AWS Region and Service Name. 

Postman options:

Hello, did you ever find a solution to this? I am working on the same kind of issue where my authentication needs to have the service and it does not using the RequestAuthAWSV4Signer script.
