Augmented Summoning is effectively Augmented Subschool (Conjuration (Summoning)), so along those lines...

Augmented Subschool
You have mastered a particular subschool of magic.

Prerequisites
Spell Focus in the relevant school of magic for the chosen subschool.

Benefits
Choose a particular subschool of magic. You gain the benefits described below whenever you cast spells from that subschool.

You may apply [Metamagic] feats to spells from the chosen subschool without increasing their spell level or casting time.

Scrying
You may cast scrying spells even on creatures, places, and items that you are completely unfamiliar with or with which you have no connection.

Summoning
Creatures you summon gain a +2 enhancement bonus to each of their ability scores. This bonus increases to +4 at caster level 6th, and to +6 at caster level 12th.

Shadow
Your shadow spells are 1% more real per caster level.

Special
You may select this feat more than once, choosing a different subschool each time.

A wizard may select this feat as one of her bonus wizard feats.
