How do add a page to an specific section (InDesign)?

[Leonardo28018229ppwn]

Hi, I want to add the selected page to the section that starts on the next page (543). I thought I could just drag the little arrow above to the page, but it won't work. Need some help pls

Triangle above the page shows where section starts - you can't move it. 

What exactly are you trying to achieve? 

Do you want to add new contents instead of page 543 - and move contents of the page 543 to 544?

Yes, that's what I want

On page 542 - add a new page and it should appear after page 542. 

543 will now be 544 and should still have the triangle.

To adjust section markers (the little triangle)
