CITECT SCADA 2018 - SELECT THE PAGE THAT SHOWS UP FIRST WHEN THE PROJECT IS RUN

Hi all,

I am designing graphics for a project by CITECT SCADA 2018. I have a question: Is there a way to select the page that shows up first when the project is run?
For example, I have 4 pages: A, B, C, D. The first time I ran the project, I chose page A to be the first display page, but now I want to choose page B to be the first display page. How to do it?
