What problem are you facing?
I am using aws jet provider groupTag to add tags on autoscaling group.
https://doc.crds.dev/github.com/crossplane-contrib/provider-jet-aws/autoscaling.aws.jet.crossplane.io/GroupTag/v1alpha1@v0.5.0-preview
But it adds only 1 tag and multiple tag entry is not supported.
How could Crossplane help solve your problem?
terraform grouptag adds the tag using for loop but in crossplane for loop is not supported.
https://registry.terraform.io/providers/hashicorp/aws/latest/docs/resources/autoscaling_group_tag#example-usage
It could be easy if it supports multiple tags.
