Multiple AKS clusters with ARC and HCI

**Title**: Onboard with ARC multiple AKS clusters, each one linked to a different tenant, on a single HCI installation, linked to one single tenant.

**Description**: I have a customer that has only one HCI cluster and is looking to create multiple AKS clusters on it. Each AKS cluster will be Azure-Arc enabled and linked to a different Azure EntraID tenant, with only one tenant being the same as the parent HCI cluster.
We have understood that with the command line this could be achieved with [Enable-AksHciArcConnection](https://learn.microsoft.com/en-us/azure/aks/hybrid/reference/ps/enable-akshciarcconnection) (PowerShell), but if using ResourceBridge this cannot be done [since](https://learn.microsoft.com/en-us/azure/aks/hybrid/aks-create-clusters-portal) they have only one Extendend Location and one extended location means one resource group, one resource group means that, if customer chooses this method, every target cluster will be under same resource group (thereby the same Azure EntraID tenant)

Request here is to foresee the same functionality provided by PowerShell also with ResourceBridge.
