A page tool query in InDesign

Hello

In InDesign using the page tool has been wonderful.

In this case though, I just want to extend the page in InDesign from the bottom.
I used the page tool and change the Height but my guides and all the items have stayed in the middle basically not just being from the bottom only.

This is really annoying that you can’t just move from the bottom only.

Any suggestions?

click in the reference point icon and select the top middle box.

Also - hold down a modifier key Alt (or I think Ctrl on PC (it might be Alt too))
Then drag the page from the bottom.

So select your page tool
Hold own alt
Drag the page down
Let go of mouse
Let go of Alt
