Additional reinforcements ( Adds. bars ) in soficad

Hi ,
when i add a value for additional bars for longitudinal rebars , and say that Additional bars have different lengths from main bars , where can i specify this length, and how can i show it in framework ?

Can i specify a specific diameter for additional bars ?

And how to show this additional bars in section view ?

The question is not quite clear. Maybe you can explain a bit more in detail and add a sketch.
