Ok I am not sure if this is a way someone already made but I did this on my own.

First:I get the inner centers.

Second:I build 2 1x2 blocks and place them directly opposite of each other.

Third:I make 2 1x4 blocks and place them on the last 2 remaining sides.

This does not work on last 2 centers.

Frank Morris does this (or did at the Essen competition, anyway).

You can do this on the last two centers if you "pair up" the obliques. What I mean is, solve the two 2x2 blocks, then pair up all of the obliques so that you have essentially reduced the last two centers to the last two centers of a 5x5. Then you can solve from there without any commutators. This is probably less efficient than the normal way, but it may be easier for you.

I use that method for the last 2 centers. I'm pretty decent at it, I think. Most of the time, after you paired the "4x4" centers, about 4/8 oblique pairs are already paired up. You can pair 2 at a time with an easy setup, 3R 2R' U 2R U' 3R'. For me it's faster than the "normal" method.

Wow. That's amazing. I had never even thoght about that. I have so much to learn.
