I wonder if anyone has had success bulk editing a custom field on multiple contributions at once? I'm in the process of adding a custom field to T_KEYWORD and while we can start using it going forward pretty easily, I would like to flag about 1,500 past contributions with this field as well. I tested updating it in T_CONTRIBUTION in Tessitura Test and that was a huge failure (as in, it deleted the contributions completely...whoops).
Is this even possible?
Thnks!
