hyperview question on the post-traitement on the fields

hello,

I'm open the abaqus result (.odb) with hyperview. This simulation is multi-step.

Question :

It's possible to have a creat field output ( abaqus viewer option ) in hyperview .

This option realised son calcution or comparsion betwen step 1 and step 2.

in hyperview with derived results option is not possible to compare step 1 with step 2. This option make not only calcul on the global field output.

How to make a comparison on two steps in hyperview?
example

Stress (step1) - Stress (step2)

thank you
