How to add hogging reinforcement into this slab?

Hi,

I’m still confused how the following top reinforcement can be placed in it. The required reinforcement should not go to the end, it’s just hogging r/f so should end short, say 1/8 th the total length of the slab (the green line below).

I tried the guide link you provided. It shows, go to “types for concrete design –> surface r/f –> new surface r/f”.

But the problem is when I add a surface r/f it applies the top r/f to whole slab, how can we edit it to shorten the length of r/f?

The top reinforcement should be like this, reinforcement in outer perimeter but no reinforcement in the mid. (sorry about the drawing, I’m bad at drawing stuff)
