How to manage or target components within HCP terraform stacks

Terraform HCP Terraform

I have component.tfstack.hcl file

component "vpc" {
  for_each = var.regions

  source = "./vpc"

  inputs = {
    environment = var.environment
    region      = each.value
  }
  providers = {
    aws      = provider.aws.configurations[each.value]
  }
}

component "first" {
  for_each = var.regions

  source = "./nodes"

  inputs = {
    environment         = var.environment
    region              = each.value
    version        = "v2.1.4"
    vpc_id              = component.vpc[each.value].vpc.id
    public_subnets      = component.vpc[each.value].vpc.public_subnets
    security_group_id   = component.vpc[each.value].security_group_id
  }
  providers = {
    aws      = provider.aws.configurations[each.value]
  }

}

component "second" {
  for_each = var.regions

  source = "./nodes"

  inputs = {
    environment         = var.environment
    region              = each.value
    version        = "v2.1.4"
    vpc_id              = component.vpc[each.value].vpc.id
    public_subnets      = component.vpc[each.value].vpc.public_subnets
    security_group_id   = component.vpc[each.value].security_group_id
  }
  providers = {
    aws      = provider.aws.configurations[each.value]
  }

}

and a deployment which deploys for an environment e.g. lets say dev

dev.tfdeploy.hcl

identity_token "aws" {
  audience = ["aws.workload.identity"]
}

deployment "dev" {
  inputs = {
    # the component configuration is deployed across the regions specified below
    regions         = ["eu-west-1", "us-east-1"]
    environment     = "dev"
    role_arn        = "my-arn"
    identity_token  = identity_token.aws.jwt
  }
}

this will create [vpc, first[eu-west-1], first[us-east-1], second[eu-west-1], second[eu-west-2]]

how can I independently update the resource only in [first[eu-west-1], first[us-east-1]] with terraform stack. in typical terraform we could maybe use --target

secondly how do I take information or output from one stack and pass it to another stack e.g. lets say I have a stackA, stackB and stackC and I want to share information from stackA to both stackB and C
