Support for 'AWS signature' authentication

As part of a RESTful API call, I have a supplier that has an endpoint within AWS, which I call through GET and POST requests. Postman has an authentication type called ‘AWS Signature’ which passes parameters such as ‘accessKey’, ‘secretKey’, ‘region’, ‘service’ and ‘sessionToken’.

Can support for this authentication type be added to Katalon, so that I can utilise this application for these API requests?

Is it known whether this authentication will be supported in a forthcoming release? Is it an item on a development backlog?

What is stopping you do add the needed parametters to whatever katalon rest api request?

Is this still on the backlog, can someone please show if this is already available with 8.1.0 version.
Thanks
