How to increase floor height in the middle of a tower

Hello, does anyone know how to loft a cull index?

More generally, I want to have a bigger floor gap in the middle of my tower (series). The current loft is from one floor to the next floor. But I want it to either skip a floor (cull index: so 1st floor to 3rd floor) or increase the height of the middle gap (z unit increase/conditional?: hence the upper floors will all have to move up too)

Is this what you are looking for?

All i did was flattening the list and doing a “straight” loft.
Be careful when grafting, duplicating and using unnecessary data (like that shift list component) as it makes it harder to work.

I am also attaching a simpler definition where you can adjust the height and depth of the inclined section and replace your shift list with list item and series.
