Report on Custom Fields Across Multiple Projects with a Sum

When will we be able to report on custom fields? For example, we have a Scope custom field that we use on almost all of our projects. However, I can’t get the summary data I need from the custom field using the search capabilities aka “reporting.” Could we even just get these included in the dashboard/Google sheets report?

Minimum, I just want to get a sum of scope, per person, per project on a single view. I feel that this is pretty basic functionality, and I already use premium!

At the very least, is there any way that we can show custom field values in the search results?
