Reuse dashboards in other subtenants

In our case, we usually have a lot of uniform dashboards for our devices. At the same time, the development of dashboards goes through several quality levels. We currently map this so that there is a subtenant for each quality level (dev / test / production). Therefore, we have a requirement that a dashboard that is considered good (or a lot of dashboards) needs to be carried over to the next level. Since we are planning further subtenants, the takeover effort will continue to increase.
