How to add "exportedTagsOnMetrics" for multiple AWS namespaces

[Preeti011987]

HI,

I have a requirement, where I have to add tags from multiple AWS namespaces:

apiVersion: v1alpha1
discovery:
exportedTagsOnMetrics:
AWS/EC2:
- ProcessName
- ServiceName
- Environment
jobs:
- type: AWS/EC2
regions:
- us-east-1
roles:
- roleArn: arn:aws:iam::AccountNumber:role/role-name
searchTags:
- key: ProcessName
value: example
- key: ServiceName
value: cloudwatch
- key: Environment
value: nonprod
metrics:
- name: CPUUtilization
statistics: [Average]

If I am adding searchTags then those tags are showing only in "aws_ec2_info" metric, I don't see them in other aws_ec2 metrics.
I understand if I am adding tags in "exportedTagsOnMetrics" then I can get the tags in metric also, but it is present at discovey level, not at job level, so what if I want to have multiple namespaces for "exportedTagsOnMetrics"
How can I do that?
