What do you need help with?

How can I fill a selection with top slabs?
I tried #sel fill cobblestone_slab and #sel fill cobblestone_sla[type=top] but did not work.

Final checklist

• I know how to properly use check boxes
• [x ] I have not used any OwO's or UwU's in this issue.

I don't believe there's a way to select that

Should there be a way? Should this be turned into a feature request?
I'm wanting to use baritone to fill a large area with top slabs (slime farm), however it can only build bottom slabs.. so I'm going to have to do it all manually

I don't think you can do it with the sel command like living said but you can always make a schematic and baritone should build it and place them as top slabs
