Feature request for the Cloudformation Parameter value to be prepoluated.

### Name of the resource

Other

### Resource name

CloudFormation Parameter

### Description

1. I created a CloudFormation template which contains Paramters
2. I want some Parameters to be autopopulated from my AWS account information
3. For Eg:
OwnerInfo:
Description: Mention the name of the person creating this bucket
Type: String

For the above OwnerInfo parameter, the value should be autopopulated based on the Users AWS Account Username so that this stack can be used in any account and the user will not have a burden to enter the OwnerInfo value.

4. Please let me know if this case be considered.

### Other Details

_No response_

The request concerns CloudFormation Parameters and the OwnerInfo example, but it names no repository files, tests, or implementation entry point. Start by reviewing how CloudFormation currently handles parameter values and account identity, then define the supported behavior and acceptance criteria for automatic username population across accounts.
