How Network Topolgy can be used to see network topology diagram for more then one resource group?

Hello,

My orgnaziation is using hub & spoke architecture, and therefore we have few resource group, each resource group contains a vnet.
Clearly, we have vnet peerings & cross vnet communication.

I would really want know **if and how Azure Network Watcher Topology can be used to see relations and network diagram of more then one resource group?**
When I enter "topology" it enforces me to choose a single resource group, is there a way to avoid choosing resource group, and focusing on vnet? or choosing the whole subscription? or choosing few resource groups?

If this feature does not exist, it could be extremely usefull for my organization and I'm certain that for many other organizations as well, since it's very common to create vnets in more then one resource group, especially when working hub & spoke.

Thank you.

issue では、ファイル、テスト、エントリポイントのいずれも特定されていません。まず、Azure Network Watcher Topology が複数のリソースグループ、VNet、またはサブスクリプションをサポートしているかどうかを確認します。対応範囲を文書化するか、複数のリソースグループに対応するトポロジビューを実装して検証すれば完了です。
