Reporting services- Magnify to 150%

I have a report that has abt 20 + fields . For all fields to fit on 1 page, I have set the
font size to 6 on that report.
Howevever, when the font size is 6, the report appears very small size when viewed from
the screen. In order to see teh reprot clearly on the scree, users have to magnify it to
150% and then they are able to view it clearl on screen.
Is there any way in reporting services, where when the report is delviered on the screen,
it automatically sets it to a 150% by default, so that
way users dont have to manually change to 150% every time they view the report?

This is simple to do if you have created a windows or web application using Visual Studio 2005. However, I doubt it's possible just using reporting services and viewing it in report manager. You don't have much control over the code for report manager.
