Compress/Expand VB Server Script in .aspx Page

I'm using VSE 2012 Express.  VB code placed in class modules have expand/collapse icons ( small box with + or -) which are very helpful. 

These icons also show up in the HTML body of .aspx pages, but not in the server script included in these pages.

Is there a setting or option to have those icons show up in server script included in .aspx pages? 

Thanks
