I suspect this might be slightly tricky, because I'm not sure Blackbaud even know why this currently works! It's a bug that they now promote as a feature, but I've been told by someone from Blackbaud that they only found out about it themselves last year, even though the functionality has existed in every RE7 version.

For a long time, the "down arrow" was a kind of secret tip, passed round between RE users in hushed, amazed tones whenever they found out about it. I know of at least three instances where people built their own add-ons to allow pasting lists, not knowing that it was already possible. And yes, I was one of those people. We paid for 2 days of developer time to make it work, and then when I went to show it to one of the users she said, "oh yes, I know about the trick with the down arrow." My jaw was on the floor for an hour when she showed me!
