Improve usability of filter exclusion UI

I was trying to exclude some reports from dashboard filters today. Some of our filters are custom fields.

This was the UI presented when trying to exclude filters.

As you can see, showing the custom field ID instead of the label is not helpful and requires a trip to the admin centre to map the IDs(if you can even access Admin Centre, not all editors are admins!).
Zendesk Support says this is expected behaviour, but I think we can all agree it's not ideal. Can this be improved to show the labels of custom field instead? We shouldn't need a map list of IDs to make dashboards. Thank you.
