Custom Thank You/Confirmation Message After Form Submittted

Using MS Forms Pro, is it possible to customize the "thank you" / confirmation message after the survey is submitted? I know you can change the text, but can you also:

• have 1 of 2 different messages appear based on answers using conditional branching
• add a photo to those messages
• change the font color of those messages

I am trying to create a form for security screening that generates a red "STOP" vs. green "GO" message after the person submits which generates a visual that shows they completed the survey. I tried producing these messages within the survey as questions and sections with an acknowledgement check-box; however, you then run the risk that the person will see the "STOP" or "GO" message and not press submit at the end of the survey. That's why I want to move the messaging to after the submission!
