Again, not a duplicate, just pointing out a similar thread: Add a Terminal that Defines Default Data. This version is more generic, allowing the user to specify the fill data for any array type (clusters, etc).
(I didn't know if you intended to highlight your comment or the idea... I just wanted to provide a more direct link. Either way, you're right, apologies for the duplicate.) (And I can now see my link was the same as yours, oops, I meant to link to the top-level Idea.)
Now I see, for some reason my reply was the first post returned from that idea in my search. My intent was to link to the idea, didn't see the extra text in the link...
