Central user project/data set authorization

Currently (SR25) user authorizations (view/edit/delete/set privilege) have to be set on a per project/data set basis. When maintaining many projects/data sets it can be quite cumbersome to add or make changes in these authorization settings. In addition its also hard to see which users can do what on which projects /data set

The idea is to add a central UI where for all users/user groups authorizations can be set on every project / data set.
