Request for Concatenated List Output in Prompts

I haven't seen a way to add a child object list of outputs (e.g., claygent's "steps") into another prompt without having to add each item individually. Would be great to have a way to add the concatenated list of items (no matter how many items there are. From what I've seen, when you "insert all 6 items" it only outputs the number of items that there are. Is that right?
