This is something rather simple. I would like the option to assign a multi-value field a new value, but have it append and become the first value in that field.

Say the field will be updated by workflow to have newer more relevant information based on new information in a database, but we still want to keep the original values intact for searching purposes. We would like to not have to go through so many steps to have the workflow retrieve, and then overwrite the existing values with the new value followed by the old/retrieved value.
