I want here this type of relationships as shown in below screenshot.

It doesn’t appear there, that is just a limitation of the Workflows module.

You need to work with Logic Hooks to get the degree of control you require. If you don’t feel comfortable with Logic Hooks I recommend an increased training in basic PHP.
