#### Description

When using a vendor-created image as the source of our "parent" images, its parent is blank. The only way I've been able to find this information is using the [API](https://developer.hashicorp.com/hcp/docs/packer/manage/ancestry#view-untracked-artifact-parent-ancestry).

```
image_version = "latest"
image_sku = "8-gen2"
image_publisher = "RedHat"
image_offer = "RHEL"
```

Having this information tracked or exposed in the UI would be much more friendly than forced to API calls.

#### Use Case(s)

Able to quickly determine our parents' parent image. Maybe some mechanism to deny certain vendors, skus etc.
