I kind of know the answer to this question already. Currently it is not possible. But I would invite you to vote for my idea on the Customer Influence pages.
In a corporate, decentralized setup like ours, "flat" space management will not suffice to build up a true data fabric.
Hence I launched the idea to have hierarchical space management available.
You can find my idea here:
In our company, we cannot simply categorize spaces in business streams. Having one space for "Sales" for instance will not work as we work in a very decentralized way. We would need the ability to manage spaces in a hierarchical way to be able to manage our complex company structure.
It could be organized in different hierarchical order depending on how a company is structured, including "sub" administrator spaces.
What is the opportunity/problem the request will address?
In our company it will be impossible to manage spaces correctly otherwise. And this from an IT, security and specially functional point of view.
What is the expected benefit?
Flexible space management, with multiple layers allowing to closely align with the way the business is set up.
