Tagging AWS Services with custom tag

Question

Hi,
I have multiple environments in my account like dev,test,prod etc.. In my aws bill, i want to segregate bill based on environments. I have already tagged resources with a custom tag "Environment" using AWS Resources Groups & Tag Editor service. However there is a portion of the bill which still accounts for untagged resources.
I made some digging and found the services that are not tagged - Cloudwatch, AWS Support, SageMaker, Quicksight.
Guide me on how to tag these resources using the custom tag "Environment", so that I gave segregate the bill as per environments.

Thanks

Hi, not all services will allow you to tag all their resources, but you can tag at least some of them to improve your cost splitting.

1. For CloudWatch, see https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch-Tagging.html View section "Supported resources in CloudWatch" to see what's supported
2. Sagemaker: https://docs.aws.amazon.com/sagemaker/latest/APIReference/API_AddTags.html.  It says 
```
You can add tags to notebook instances, training jobs, hyperparameter tuning jobs, batch 
transform jobs, models, labeling jobs, work teams, endpoint configurations, and endpoints.
```
3.  For QuickSight: https://docs.aws.amazon.com/quicksight/latest/APIReference/API_TagResource.html
```
Amazon QuickSight supports tagging on data set, data source, dashboard, template, and topic.
```
