Dave, yes, concatenation of each result would be really great! I hope it's possible.
BTW, concatenation would like also likely solve a problem with the way Sequence IDs work in Key Summary Reports for multi-line Regex searches. As far as I can tell, FLP 8 now assigns a Sequence ID to each separate line of text returned in in multi-line search, rather than each separate search result. I'm pretty sure that is not an intentional/designed behavior, but an artifact of extending FLP to support multi-line searches. Hopefully, concatenation would fix that problem as well.
I've include a screenshot of what I mean at the bottom of my original post.
