I have two layouts that repeat on two pages: two panels at the top and one big panel at the bottom. And this looks like a layout I might want to use in the future, so I went to YouTube to find a tutorial on it -- and found a great one.
The video is about 10 minutes long, and WORTH WATCHING in its entirety. However, if you just want to know how to save a design as a custom layout (i.e. material), then jump to the 9 min mark.

Update Oct. 08, 2017: Turns out, next time we're talking about workflow issues. I'll get back to character design shortly.
