[O] Return header one level up

[Zach Sheffler]

I'm trying to dip my toes into the waters of customizing org-mode somewhat, so I'm unsure as to where to look.

Is there an easy way to return the text of the parent header? In other words, if I had this in the agenda prefix, and the agenda file read:

* One

** TODO Two

It would show in the agenda as

Todo: (One) Two

?
