How to hide automatically navigation panel

Hello,

I wanted to create menu with buttons with all pages I have in my report. I wanted to have it automatically so everytime I create new page there will be additional button visible in menu so I used Buttons->Navigator->Page Navigator. I wanted also to have a possibility to open and close the menu so I created shapes and buttons to hide and unhide the menu. The problem is that when you unhide the menu and click the button to go to selected page, and then you go back to the previous page- the menu is still open. I would like to find the solution to close the menu automatically to avoid additional clickig "close button" everytime i go back.

(I know that there is a possibility to create separate buttons for each page and assign the bookmarks with option to "close menu" intead of navigation page but with this option it is not possible to automate it that there will be new button when the new page will be created).
