Manga Studio (aka Clip Paint Studio): How to Save Custom Panel Layouts

I'm working on the Days Gone comic story, and am doing my first multi-page file in Manga Studio 5 EX (this is one of the few differences between the PRO version and the EX version: the ability to have multiple pages in the same file). The advantage to this is that it will maintain consistency between the tone frequency and panel border thickness -- all useful things in a story (as opposed to doing it manually page-by-page).

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.
