I think you don't need to do anything to pass filter from primary dashboard to 'jump to dashboard'. Whatever filter applied to that blox widget(including dashboard filters) will get propagated to 'jump to dashboard'.
Here is the list of all configurations available in Jump to Dashboard plugin:
drilledDashboardPrefix : "_drill", // The prefix of the drilled dashboards name.
drilledDashboardsFolderPrefix : "", // The prefix of the folder the dashboards inside which can be drilled to.
displayFilterPane : true, // Display filter pane in the drilled dashboard window.

drillToDashboardNavigateType : 1, // Default navigation type for widgets
