I do not see any native solution to this; you would likely need some custom programming to populate a field with the value; but you would probably need to invoke the code somehow; or schedule it to run as I doubt it would be dynamic.
You can "view" this data from within a parent-record by use of a Report Link field. Then build a custom-report which shows all the child-table records with only the [Something] field visible. The downside to this is that you would need to be inside the record; and if you had 500 children, you would have pages and pages of records to click through.
