When attempting to delete data assets (queries etc) - I commonly come across the error "Unable to delete contact source. Contact source has references in one or more of the following: mailing queries". This error is no use to anyone! It would be great to list all queries/databases which would need amending, to achieve the delete.

Recently, it was quicker for me to hunt through 40 possible queries, to find the culprit. Faster than support getting back to me! My Master1 database has nearly 2.5k queries - this would be impossible to search through.
