Adding New Page Types in Dashboard

Permalink
Hi.

I did a search for my specific issue, but didn't see anything that addressed my question in a precise manner.

In the dashboard under Pages and Themes -> Page Types, there are 4 layout images. I need some direction with an approach to add additional layout templates via the established interface. In other words, i want to create additional grid layouts which a user can select using the radio buttons. So instead of four simple layout possibilities, I can create X additional layouts with different grid stacks.

Any suggestions?



Thx
