SSRS | Jump to report

Hi we are using SSRS 2008 to develop our reports. To navigate one report to another reports we are having two option 1. Jump to report 2. URL option.
We are using these two option to navigate our reports. While exporting this to PDF or Excel, the URL option is working fine in PDF too[(i.e) we can able to select the link in PDF also], but the Jump to report is not showing any link to select. How to reslove this.
