Organising Projects in GitLab

Hi - is there a way to organise projects in the dashboard of GitLab? I will have many projects which will be related (such as a bunch of microservices) - each of which will have its own GitLab project (or repo) but in essence really come together to form a real-world Project.

So, is there a way to either tag the Projects (different from git tags) and then filter on that tag or create a namespace some other way.

Many thanks
