How to get a count of the projects with specified metadata

[Kate Reeder]

Is there a way in Atlas (Platform Experience) to get a count of projects with some specified metadata. For example:

• how many projects have a certain tag
• how many projects are owned by a certain person
• how many projects are in a specified status 
• how many projects are with a specified custom field value

I know I can just run a filter and manually count them, but I'm looking for a systematic way to count them. I also understand I can export to CSV, but the csv doesn't contain custom fields and exporting then counting is still a manual process.

Just discovered how to get systematic counts on tags, but still don't have a solution for owners, statuses, or custom field values. 

For Tags - in the Project Directory, click the button to 'Filter by Tag'. The list of available tags will display and the count of usage for each is displayed under the tag name.
