Hyperlink Target property in SharePoint 2007 Report Viewer Web Part

SharePoint 2007. I have the SSRS Web Part embedded in a page as part
of the dashboard. The SSRS Report displayed in the SSRS Web Part
contains a link (aka Jump To Report) to a second report. I want the
second report to open in the parent SharePoint page, not in the Web
Part.
The Web Part contains a property called "Hyperlink Target", which
should specify where hyperlinks are opened. Even if I set this
property to be "_blank", the second report opens inside of the web
part.
Had anyone been able to use the "Hyperlink Target" of the Sharepoint
2007 SSRS Web Part?Anyone?
