BI Launchpad preference on content

Hello ,

I have a requierment ,In 4.1 SP2  When a user/group open WebI reports ,

use the "Set document viewing location" preference as "In the BI launch pad portal as tabs"  and when the same user/group open a dashboard , use the setting as "In multiple full screen browser windows, one window for each document" . Looking for a way to set this preference based on the type of content like Webi , Crystal , Dashboards etc...

Thanks in advance

Thomas
