Ability to Have "Shortcut" report links with Rolling Dates



When creating a "shortcut" (tiny URL) link to a SiteCatalyst report, I woudl like to have the option to make this rolling with respect to date ranges like bookmarks and dashboards do...This would allow me to post these links on the INtranet and elsewhere and know that when users click on them, they will see the report I want them to see, but for the current date range (day, week, month, year, etc...)
