Anyone made/seen a merge/replace items in list reporter?

[cymplecy]

I thought I'd made one myself in the past but can't find it

So looking for something that will merge two lists into one in this manner e.g
merge the two top lists to produce the bottom one - empty slots in first list to not be merged

[dardoro]

The simplest case, exactly matching your example

Ta

Obvious once I've seen it

Made it into a reporter

Maybe "fill blanks"
