It would be extremely helpful to have the ability to Query for records that have multiple instances of a specific constituency code on the same record.

We record Spouses on the same record, so if they're both "School Alumni" there would be two "School Alumni" constituencies for them on the record.  We use conditional language in our appeal letters to say "As an alum, Constituent X, you are...", but the conditional is incorrect unless we set up a specific salutation for alumni records, for example.  We could add something to track that for future records, but it doesn't solve the problem of finding existing records with multiple instances of the same constituency code on one record.
