You can go with main page, and than add a layout to the area. Intead of adding a block add an area and you can set as many columns or rows that you would like. An easy way to do this is to add the 3 column, 1 row default, and use the left column as main, middle column as a spacer, and the right as a sidebar, or vice versa. The sliders can be moved to create as much or as little space as you want to each area.

The other way is to create a page type with .php, and put it in your server than link the page type in the dashboard.

I tried to add a layout, but since it's already split into 2 columns (the main section and the sidebar), it just adds it over one or the other.

I need to supercede the 2 columns and have one column above the 2.

I really don't want to mess with the php, that's how into trouble before.

Isn't there another way? I thought of changing themes to plain yogurt, do it there, and change back, since that's what I started with. I think there are more options and it looked ok there.

Brilliant! That is exactly what I needed! Thank you!
