Can we get search results which include the Address "Override" checkbox? Customer wants to tidy up the override addresses.

I believe you should be able to if you join to address and bring the field in. it's a checkbox, so perhaps a formula that outputs customer-friendly text when checked and blank when not checked to make it easier to digest.

Tried that yesterday. The field name is {override} also tried {address.override}

What record are you attempting to join from?
