The Scenario

Imagine you have a group of customers who use your instance, and none of them are allowed to see the content from another company. Thus, you manage to restrict the spaces for each individual group, and now wishes to set up the Site Homepages (whenever someones access the instance), and redirect those users to the space from the group they belong to

Current Scenario

You can't, Site Homepage is configured for all Confluence users

Expected Scenario

You would be able to configure the homepage for each group individually
