Is it possible to force the page tree in the left sidebar to open by default when you access a page?

I need the page tree contained in the left sidebar to open showing all levels of the tree when a page is opened. Is that possible?

Hi Lisa, if you have a some macro for theme, you should have a Space Layout in menu where is Space Tools. 

There you can open a block where is macro for page tree, edit it and then set level of expand.
