We have organized our workspace hierarchy in a particular way, and would like to have reports (pivot in particular) reflect that order of workspaces. In addition to alphabetic sorting, it would be great to have "hierarchy order" or something like that as an option for workspaces. An alternative would be to expose the workspace order as a build-in field available for reporting and sorting on.
We have run into the same issue and now that we provide customers a view into our roadmap through the ideas portal its even more important to have some way to sort the workspaces. It is very confusing to have a blob of workspace names with no way to sort them.
