Calculated “Title Attribute”

And yes, "aggregate fields" would be nice - I'm assuming that you mean some type of Summary Total of a given field over a group of selected records.

Haven't spec'd it out yet, but from memory:
(a) Aggregate field = sum of specified attribute for a specified item type.
(b) Include in summation only a parent's child items, (as linked in Data Explorer), that are of the specified item type.
(c) Total to be available for presentation in custom form.

Also got written down, sorry, typed up, the crazy notion of somehow showing aggregate field in a Footer or Header pane below/above Child Items pane aligned with respective attribute column.
