Looking for a psionic feat

[The Vorpal Tribble]

Ok, I'm looking for a psionic feat that allows you to use Expanded Knowledge to learn a power up to the level you can manifest, instead of one below. I vaguely seem to recall a feat that allowed that but can't recall for the life of me.

Edit: Crap, that's Epic Expanded Knowledge... seriously, that doesn't seem worthy of an epic feat.

Oh, I'd say learning True Mind Switch, Metafaculty, or Genesis without the proper discipline could be epic-feat-worthy.

What power are you trying to access? There might be some other workaround, such as a psionic item, psi-like ability, or magic which duplicates the effect.
