(sorry for the cross post to core)
Hey everyone - I’m new to Radiant, but am loving every second of it.
The need for a parent tag came in my first Radiant project, so I
searched the lists, came upon this posting by John , and whipped up
a properly tested patch real quick.There’s a ticket  with a diff if
you’re interested in testing it out. Let me know if anyone has any
questions or if need to make any changes. Thanks!
