Workflow - Is there any way how to force to display screen in workflow with RED Save Button?

I want to achieve the following:

  1. I have a workflow where I prepare data (import data from Excel and save them into existing object)
  2. I display data in the form inside workflow and I would like to “advice” user that he needs to save form

So the best would be if the screen would display with Save button in RED color, exactly how it happens when I change the form. Is there any way to tell UI that “there were changes made into an entity displayed on the form” i.e. by setting something in transformation?

Thank you,
